Discovering the Formosa Lily (1 of 3)

From “The Species and Varieties of Lilies: Lilium formosanum” in Lilies for American Gardens by George L. Slate:

“The flowers are narrow funnel-shape, with the tips of the segments gracefully recurved, pure white within, suffused with wine-purple without, or occasionally white, fragrant, and from one to ten in number. The purple-brown stem is slender, variable in height from two to six feet, and clothed with numerous, narrow, grasslike, dark lustrous green leaves which are crowded near the base of the stem, but few in number and short below the flowers. The bulb is white, tinged with rose-purple, and nearly round. This lily is a native of Formosa from sea-level to 10,000 feet altitude, where it grows in the sun among coarse grasses in a light, well-drained, somewhat acid soil….

L. formosanum was discovered in 1858 and in 1880 the firm of Veitch in England received bulbs which they flowered. It passed out of cultivation, but was reintroduced in 1918 by E. H. Wilson. Seeds and bulbs are now generally available from American, Oriental, and European sources in quantity at reasonable prices and the lily is rapidly increasing in popularity.

L. formosanum… is a beautiful lily well worthy of a place in any garden. The pure white trumpets come in mid-September at Geneva, N. Y., the species remaining in flower until the first frost….

“Seeds of selected pure white strains are now available from various commercial sources. Seedlings, if started early in the year, may be expected to flower the first season and field-grown seedlings will flower the second fall…. In warmer climates the bulbs grow continuously, sending up new shoots which keep the colony in flower over a long period…. The Award of Merit of the Royal Horticultural Society was given to this species in 1921.”


Hello!

This is the first of three posts with photographs of an astonishing lily whose formal name is Lilium formosanum, also known by the common names Formosa Lily, Taiwan Lily, or Taiwanese Lily.

“Formosanum” in the plant’s species name reflects its discovery and its native location: the country of Taiwan was primarily known in the West as Formosa until the post-World War II era, after which “Formosa” declined in use in favor of “Taiwan.” As is often the case with the scientific names of plants, though, the designated species name Lilium formosanum wasn’t changed; but botanical literature would evolve to reflect the political realities by treating Formosa Lily, Taiwan Lily, or Taiwanese Lily all as informal synonyms for the same plant.

On July 17, I was at Oakland Cemetery photographing a variety of midsummer bloomers — including anemone, amaryllis, crinum, early zinnias, and many of the Japanese Show Lilies for my last three posts (see, for example, Lilium speciosum, the Japanese Show Lily (3 of 3)) when I came upon these new plantings. Here’s the first photograph I took:

This is not a particularly good photograph simply because the sun was too bright to properly separate the foreground from the background and clearly show one of these plants’ most distinctive features: their height. Lucky for me, though, all I had to do was turn around to find additional plantings, where the plants were growing against a shaded background provided by numerous trees. Here their height is even more apparent and now you can see their incoming flower buds, each one a long, bright yellow oval glowing in the filtered light:

Given how much of my photography takes place at Oakland, it might seem surprising that I keep discovering new species. But the cemetery is in year seven of a 20-year, $43.5 million renovation plan, which is so comprehensive that it includes architectural and structural changes, as well as the rejuvenation of and often addition to its existing landscaping. Click the first image below if you’d like to see the entire timeline; this project started in 2018 and extends through 2037.

So for this rather obsessive botanical photographer, the ongoing renovations mean that — in addition to natural changes that occur in dynamic gardens like those at Oakland — I can often encounter newly established plantings of species I’ve never seen before from one season to the next. I can even pretend to be one of those intrepid Victorian naturalists, don my floppy hat and sport my camera, slink and shoot among the flora, then return home to scour various sites and libraries to identify and learn more about the plants.

That, of course, is exactly what I did with these Formosas, and how I learned about its unique capabilities (like those I excerpted from George Slate’s book at the top): its adaptability to multiple soil and lighting conditions; its ability to reach and maintain substantial heights and even weather thunderstorms; and — importantly for my discovery — the fact that it can achieve this growth in the same year it’s planted. I can hardly wait to see how it expands its territory in the next year or two of its lifecycle.

I wasn’t sure how long it took these lilies to bloom, though, so I had planned to go back in about two weeks from July 17th and check on their growth. Summer thunderstorms intervened, keeping me away for longer than that; but I got a second look at them about three weeks later, on August 9. On that date, some of the plants had indeed been damaged by the storms, but most showed the strength and resilience that’s typical of these lilies, many now standing nearly six feet tall, with long, nodding blooms spread across their tops. The first two photos in the galleries below provide a wide-angle view of about 15 plants at the intersection I show above; the rest (and those in my second post) are from both locations I show above, from various angles and distances to adequately represent all this lily plant’s characteristics.

In the third post in this series, I’ll show these same lilies in a different location, where they’re tucked near an Oakland pond and surrounded by ferns. The three posts together demonstrate yet another characteristic of this lily: its ability to thrive in a variety of conditions that other lilies would find intimidating. These three locations show the lily capable of excelling in: full-day sun with sandy soil; part-day sun with more compact soil it shares with smaller plants like amaryllis; and towering above thick ferns, where the sunlight is diminished and the soil — supporting the ferns — is more like that of a shade garden or even a bog. These characteristics help account for the excitement about this lily in the quotation at the top of this post, especially given that the lily achieves this level of growth in the very same year its bulbs are planted or its seeds are sown.

Thanks for reading and taking a look!









Lilium speciosum, the Japanese Show Lily (3 of 3)

From Atlanta’s Oakland Cemetery: An Illustrated History and Guide by Ren and Helen Davis:

“In nineteenth-century New York, Boston, and Atlanta, the provision of burial places was another new municipal service that local governments were forced to provide as a result of their burgeoning populations. The dead became too numerous to be buried in the churchyards that had served colonial-era towns….

“Boston, whose population topped seventy thousand in 1830, created a model for addressing the burial needs of its citizens. The city government did not establish a city cemetery; rather, it delegated the task to the not-for-profit sector. Like most large urban centers, Boston had its share of voluntary associations dedicated to promoting the common good, one of which was the Massachusetts Horticultural Society. The society decided to combine its interest in flora with the city’s need to bury the dead, so it created a ‘garden cemetery,’ a place where the dead would be surrounded with trees, shrubs, and flowers. The place envisioned by society members was to be not just a burial ground visited by the families of the dead, but also a destination for the living of Boston, a place where its residents could come to see a landscaped garden….

“In his 1831 address at the dedication of the cemetery, named Mount Auburn, Joseph Story explained that the crowded conditions in Boston, which is surrounded by a harbor and tidal waters, necessitated the location of the cemetery in the countryside, well beyond the city limits. Because of this, he called Mount Auburn a ‘rural’ cemetery, a descriptive that was applied to garden cemeteries in other cities….

“Other cities quickly adopted the Mount Auburn model, establishing private societies that purchased rural land, landscaped it, and sold the first lots to a wealthy elite. Philadelphia established Laurel Hill in 1836; Baltimore, Green Mount in 1838; and New York City, Greenwood in 1839. The multiple functions of the rural cemetery fit into an emerging consensus among progressive thinkers about the need for civic improvements in American cities….

“Established as a burial ground, the Atlanta City Cemetery acquired greater cultural and material significance because of its hilly location and the course of its development. Twenty-two years after its establishment, with expansions, the erection of monuments, and the growth of a cover of oak trees, the cemetery was renamed Oakland. It had become a garden cemetery with artistic monuments…. America’s larger urban centers incorporated the garden qualities of the cemetery, park, and suburb into their expanding perimeters from the 1820s to the 1870s. It was in the 1880s that Atlanta became large enough to support these developments, and Oakland Cemetery led the way…. “


Hello!

This is the third of three posts with photographs of the Oriental lily Lilium speciosum — also known by the names Japanese Lily and Japanese Show (or Showy) Lily. The first post is Lilium speciosum, the Japanese Show Lily (1 of 3), and the second post is Lilium speciosum, the Japanese Show Lily (2 of 3).

In my last post, I introduced these three photos, which show where the Japanese Lilies are located:

The photos show the kind of integration — across history, culture, landscape design, botany, and historical memory — that was common during the rise of Victorian garden cemeteries in the United States from the middle of the nineteenth century. The entire plot is bounded by a short concrete wall on all sides, one that separates the space from those surrounding it yet still provides visual and physical access to the family memorial from any direction. More than one structure is present within the plot’s boundaries, a common occurrence in spaces like this. In this case, though, the bell-shaped monument has a ragged break at the top — one that wasn’t caused by aging but was sculpted that way, probably to represent a life cut short. The presence of grass, ferns, shrubs, and flowers within the same space softens the appearance of the monument’s more harsh stone structures, creating calming shadows while adding contrasting colors to its other visual characteristics. These elements all come together as staging for a story and a history, one that is simultaneously a narrative containing family memory while potentially indicating a family tragedy.

This space actually memorializes members of two families related by marriage — that of Daniel Dougherty and Patrick Connely, who both died in 1851, so it’s likely that the tall monument was constructed and erected around that time. The Dougherty name is inscribed on one side of the monument; the Connely name on another. Connely died of natural causes but Dougherty was murdered by a perpetrator who was never identified — an event that lends credence to the idea that the broken monument represents a tragic circumstance. The inscriptions on the broken monument are no longer legible, so this may be speculation on my part; but even if I’m wrong, you can see how interpreting a historical space while recognizing the symbolism of something like a broken structure can lead to reasonable conclusions about its original intended meaning.

You can read a bit more about Dougherty here, and Connely here; and read about the family relationship on Oakland’s Irish Resident’s page. The square building to the right of the monument is not part of the Dougherty-Connely memorial, but is that of Timothy Burke, another Irish immigrant to Atlanta who’s also mentioned on the same Irish resident’s page. It’s quite common — especially in this old section of the cemetery, its Original Six Acres established in 1850 — for memorial spaces to appear to merge from certain angles simply because they’re so close to each other, which was perhaps another reason the Dougherty-Connely section has boundaries defined with a wall.

These three photos also illustrate another defining principle of garden or rural cemeteries: their blend of constructed and natural elements that were intentionally planned to combine the two. The movements that created this element blending — which started with Mount Auburn Cemetery in Boston — evolved from a confluence of several emergent nineteenth-century concerns: rapidly growing populations in U.S. cities and the resulting need to expand cemeteries; backlash towards the unrelenting effects of capitalist progress and its effects on the environment; and rising worries about how urban centers detached human beings from the natural world.

Garden cemeteries like Mount Auburn or Oakland — often called “rural cemeteries” to reflect their design rather than their location — were proposed and developed with these concerns in mind. They were created as memorial spaces that served multiple purposes simultaneously, including that of providing a resource for living residents to explore history, architecture, and nature not far from their homes. The compressed history I excerpted from Atlanta’s Oakland Cemetery: An Illustrated History and Guide at the top of this post connects Mount Auburn’s development to Oakland’s; and the book Arcadian America: The Death and Life of an Environmental Tradition by Aaron Sachs takes up their representation of nature and the environment, starting with an evocative description of Mount Auburn and leading us to its nationwide influence:

Many Americans came to see Mount Auburn as a new paradise. Their experiences of the cemetery, though, suggest a garden not of carelessness but of caring — not of gratification but of gratitude. It was a grounded, earthly Eden. Within just a few years, Mount Auburn became perhaps the leading tourist attraction of the young republic, often mentioned in the same breath as Niagara Falls and George Washingtonโ€™s estate at Mount Vernon….

The cemetery offered serenity but also excitement — a sense of seclusion in sheltered dells, but also the confusion of labyrinthine trails and the stimulation of broad views…. It taught the ravishing beauty of autumnal decay, the Romantic pleasure of melancholy. It suggested that the fullness of life could be tasted only through a constant awareness of death. It offered the consolation of regeneration even as it reinforced the pain and anxiety of limitation. It was an asylum, a sanctuary, but not necessarily an evasion. Visitors sometimes came to the cemetery not just to recuperate from modernity, but to rethink their role in it….

Both men and women spent their leisure time at Mount Auburn…. The cemetery clearly cultivated a spectrum of emotions, and it was large enough to accommodate expressions of both joy and grief, but most people at Mount Auburn seem to have experienced a reverent, satisfying mixture of the two….

This embrace of social unity, of a public spirit manifested in environmental terms, of wild nature as a tonic and a countervailing force against a hubristic Progress, was expressed by civic leaders again and again, in Philadelphia, Baltimore, Brooklyn, Rochester, Albany, Pittsburgh, Cincinnati, Providence, Louisville, Savannah, Charleston, Richmond, Buffalo, Detroit, St. Louis, Milwaukee, Atlanta, New Orleans, Memphis, and Cleveland — each of which consecrated a nonprofit rural cemetery between 1836 and 1853.

Taken together, these developments show us how garden cemeteries have evolved to embrace so many cross-cultural characteristics. Grounded in both history and nature, we see why it happens that a place like Oakland contains such a mixture of often-exotic plants and flowers, while simultaneously representing Georgia-native and naturalized flora and fauna within the same physical space. And much of its architecture takes all this into account: it’s common for monuments like that of the Dougherty-Connely families to mirror the landscaping around it. Here, for example, we can see how the monument’s carvings are not incidental or accidental: from top to bottom, fleur-de-lis that resemble the lilies planted at its base are sculpted in stone…

… likely proscribed in the initial design of the memorial, then maintained in historical continuity for the next 175 years. The monuments reflect the landscape, and the landscape is constantly being developed and revitalized to reflect the art and symbolism in the monuments, throughout that entire time.

Thanks for reading and taking a look!












Lilium speciosum, the Japanese Show Lily (2 of 3)

From “Lilies: The Next Generation” in Lilies: Beautiful Varieties for the Home and Garden by Naomi Slade:

“The Victorian passion for botany is legendary. Daring chaps dashed around the globe and new species poured into gardens to the delight and amazement of all who beheld them.

“But gather plants together and, sooner or later, hybrids will emerge; sometimes naturally but often as a result of an irrepressible human desire to improve on nature. While fabulous, lilies had gained a reputation for being challenging and capricious to cultivate. They were exciting; they were expensive; and they were quite likely to die on you after a couple of years. Inevitably, they attracted a certain type of well-heeled horticultural brinksmanship, right up until amenable
Lilium regale emerged, bringing down both prices and the level of skill required to cultivate this most desirable of flowers.

“The backroom boys of experimental horticulture were already on the case, however, and as early as 1869, Francis Parkman, a hobby horticulturist in Boston, had successfully crossed
L. auratum and L. speciosum….. Progress accelerated and by the Second World War the hunt for better, brighter, more glamorous and, crucially, more reliable flowers was well underway.

“The man who really kick-started the lily revolution was Jan De Graaff. In the late 1930s he gathered the best forms of the species and the available hybrids of the time and began a largescale programme of hybridization at his nursery, Oregon Bulb Farms. In 1941 he struck gold with โ€˜Enchantmentโ€™, a variety that is still with us today. The legions of plants that followed were a revelation: a reliable, spectacular and versatile legacy that has been taking the world by storm ever since.”


Hello!

This is the second of three posts with photographs of the Oriental lily Lilium speciosum — also known by the names Japanese Lily and Japanese Show (or Showy) Lily. The first post is Lilium speciosum, the Japanese Show Lily (1 of 3). As with the previous post, my photographs show this lily in a variety of lighting conditions, where fast-moving clouds switched the sun on and off, or I took photographs near the sides of their monument where they were shaded by nearby trees or by the monument itself.

Here are three photographs of that monument — one of the oldest in Oakland Cemetery, located in its nineteenth-century Original Six Acres — from a set of images we’ll explore in the third post. As you can see from the photos, approaching the monument from different sides can mean taking advantage of varying kinds of light, to produce photographs that demonstrate the effects of full sun, full shade, side-lighting, or backlighting on this lily species. These conditions provide different micro-climates for observing the lily’s growth and flowering, and also let photographers experiment with the effects of different environments on images and color reproduction.

The excerpt from Lilies: Beautiful Varieties for the Home and Garden above introduces two important contributors to early and modern lily breeding, Francis Parkman and Jan De Graaff. Parkman — more commonly identified as an adventurer, historian, and author of The Oregon Trail — was also an avid horticulturalist. De Graaff — a member of the De Graaff family whose horticultural and flower breeding businesses extended from the 1720s in the Netherlands to the mid-twentieth century in Oregon — was noted for his lily expertise, and the family business was involved in breeding and selling not only lilies, but also daffodils, irises, and tulips for more than three centuries. De Graaff’s lily expertise led him to an appreciation of one of Parkman’s singular contributions to lily hybridization, crossing the two botanically significant species Lilium auratum and Lilium speciosum — both of which contained substantial genetic material that has informed much subsequent lily development.

In his book Lilies, De Graaff describes Parkman’s contribution like this:

“Crosses between auratum and speciosum are among the most important and are the loveliest of the new garden lilies. Some have been produced in New Zealand, others in Australia, and many in Oregon….

“But it is of considerable historical interest that this cross was one of the first ever made between two species of lilies. Francis Parkman, the American historian, growing both species in Boston, pollinated a number of L. speciosum flowers with pollen from L. auratum. The cross must have been made about 1864 or 1865, for the seedlings flowered in 1869….

“Of these seedlings all but one looked exactly like L. speciosum. The one exception was spectacular, a plant with scented foot-wide flowers having segments crimson on the inside, with a white edge. Parkman increased the stock of bulbs by offsets, and then sold them, about fifty, to the great English nurseryman, Anthony Waterer. The lily was named L. X parkmanni. It became infected with virus disease and was totally lost. The cross was repeated, or one very like it, in England by P. S. Hayward in 1914 and by other gardeners elsewhere, but all these earlier auratum X speciosum lilies were lost, owing to virus disease or to some other accident. Real stocks of bulbs of such fine garden lilies were not propagated until the last decade or two.”

This excerpt acknowledges Parkman’s accomplishments, while elsewhere in the book, its cultural importance is recognized. The book’s introduction describes how “the cultivation of LL. auratum and speciosum in mid-nineteenth-century England, [created] an horticultural furore and a craze for these flowers which thus displaced the old lilies and became the lilies par excellence.”

This history, then, not only gives us a short tour through the ups and downs of lily hybridization, but also locates their cultural impact. Parkman’s original crosses were produced, then lost, then resurrected in different forms, and along the way a hybrid was produced — Lilium x parkmanni — that was distinctive enough to be treated as a separate cultivar and named after its progenitor. At the same time, subsequent expectations for lily hybrids were permanently altered from earlier, less dramatic forms to forms and colors like those of Oakland’s Lilium speciosum descendants — large, multicolored, complex, and vibrant plants that now adorn our memorial and personal gardens. That the botanical history of this turn towards more striking lilies coincided with the early development and landscape planning of Victorian garden cemeteries is something we’ll explore in the next post in this series.

Thanks for reading and taking a look!










Lilium speciosum, the Japanese Show Lily (1 of 3)

From “The Journey of the True Lily” in Lily (Botanical) by Marcia Reiss:

“Hybridization has produced an astonishing variety of lilies in nearly every colour, shape and size. More than 15,000 have been listed on the International Lily Register and just as many unregistered hybrids are believed to exist….

“Beginning in 1963, two standard-bearers of the lily world, the Royal Horticultural Society and the North American Lily Society, established an internationally accepted system of nine different divisions. Like the hybrids, the number of divisions kept increasing, but the eighth conveniently includes those not accounted for in any of the others…. The divisions are based on the species used to create the hybrids, distinctions that can be confusing to the average gardener. There are separate divisions, for example, called Asiatic and Oriental — a division that appears to be redundant….

“Asiatics, largely the hybrids produced at the Oregon Bulb Farms and their descendants, are beautiful, virtually pest-free and amazingly hardy. Their only drawback is that, for the most part, they are also fragrance-free. Orientals, mainly derived from the two Japanese stars of the nineteenth century,
L. auratum and L. speciosum, are very fragrant and flamboyant in size and colour. These two species had been crossed as early as 1869 by Francis Parkman….

“One of the most successful Oriental hybrids, the colourful and fragrant โ€˜Stargazerโ€™, was finally created a century after Parkmanโ€™s milestone. A cross between
L. henryi and L. speciosum rubrum, it is a show-stopping beauty with crimson petals edged in white and sprinkled with dark red spots.”

From “The Lily Plant” in Lilies for American Gardens by George L. Slate:

“The flowers of lilies are diverse in form and color and it is this diversity which contributes to the charm of the genus. On this diversity of form and the position of the flower is based the classification of lilies.

“The parts of the flowers are in sixes. The outer part consists of three petals and three sepals which together are called segments and make up the perianth. Within are six stamens or the male part of the flower. These are composed of slender filaments at the top of which are the anthers or pollen-bearing organs. The pollen varies in color with the different species from yellow to dark brown and is of some taxonomic value. In the center of the flower is the pistil, or female part of the flower. At the base of each segment is a narrow groove, the nectariferous furrow which secretes nectar….”


Hello!

This is the first of three posts with photographs of Lilium speciosuman Oriental lily whose common names include Japanese Lily and Japanese Show (or Showy) Lily. It does live up to its “showy” moniker: the plant blooms profusely over several weeks, often with a dozen flowers per plant, each flower showing rich and reflective shades of red, purple, or magenta colors that vary depending on the lighting provided by the sun or the way light bounces off their surroundings.

As you progress through the photos below (and those in the next two posts), you’ll see the effects of those varying lighting conditions: note how the petals of those photographed when the sun was out are redder than those taken in the shade, those taken in the shade shift more towards purple, and those with gray stone backgrounds shift from warmer red or purple tones to shades of magenta. Unlike the Tiger Lilies (Lilium lancifolium) that I presented in previous posts (see Capturing the Elusive Tiger Lily (1 of 2) and Capturing the Elusive Tiger Lily (2 of 2)) — which demonstrate a consistent, saturated orange color largely unaffected by lighting variations — the more translucent petals of Lilium speciosum may look completely different as conditions (or your standing positions when photographing them) change.

I identified this flower by uploading about 20 of my photos to PlantNet, which reported a 60- to 80-percent likelihood that Lilium speciosum was the correct species. Those are actually very high percentages; most flowers I identify that way are not nearly as recognizable, and I’ll use additional sources to try and get them right. Even so, though, the quotation at the top of this post suggests how complicated the genetics of any one lily plant can be, and this Lilium speciosum — one of the most important lily variants, whose botanical history we’ll explore in the next post — shows evidence of potentially having the spots, colors, and petal shapes of many of its predecessors, in its own distinct package.

I initially discovered these plants producing flower buds on June 21, where they surround the base of one of Oakland Cemetery’s prestigious monuments, which we’ll take a closer look at in the third post in this series. I took only three photographs that day, capturing the plant in its budding stage, where one of its distinguishing characteristics — the large number of blooms it can potentially produce — is evident.

Three weeks later, we see how that potential plays out in these photos showing one of the plants with four flowers in full bloom (Lilium Flowers describes how the blooms unfold), along with six styles that have previously shed their flower petals. So this plant was capable of producing ten flowers from a single stem emanating from the ground, each flower balanced on branching “tributaries” (just as the buds were) and positioned to offer pollinators opportunities to approach from varying directions. The flowers also demonstrate the typical staggered blooming strategy of many lily plants, a strategy that extends the plants’ accessibility to those pollinators from several days to several weeks.

Its extended blooming period gave me a chance to observe this Oriental lily in more than one stage of its lifecycle, even though I took most of the photographs on a single day. Below, in this image, we get a closer look at what happens after the flowers have finished blooming, where the styles to the left and right of the stem curve upward as a reminder of the original positioning of the flowers. We can’t tell from looking at this photo if pollination actually occurred; but if it had, then the stigma at the end of these styles would have been brushed with pollen by some fly-by bugs or the wind, beginning the next reproductive stage where the flower’s seeds get fertilized in the seedpod closer to the stem. We often see styles like this in our gardens; the fact that we may visually tune them out (or, as I have often done in the past, remove them from photos) suggests that we may not realize their significance, but I think we should — especially when they’re as artistically placed as they are in this photo.

This Japanese Show Lily shares the same Turk’s Cap form with Tiger Lilies, yet also demonstrates important differences. The two plants appear to take divergent approaches to managing their reproductive energies, with the Tiger Lily emphasizing large, heavy blooms to attract bigger pollinators, fewer flowers per plant, and a backup method of cloning itself with bulbils. The Show Lily doesn’t generate bulbils, but instead produces many more blooms on each plant, any one of which is smaller than that of a typical Tiger Lily. This larger quantity of blooms also introduces architectural differences between the two plants, with the Show Lily building an array of stems constructed like a scaffold to help distribute mechanical stress and send nutrients to the flowers and leaves.

The Show Lily’s flowers are also not only smaller than the Tiger’s, but — as you can see from most of the photos — their recurve is not as tight as that of the Tiger Lily. This keeps the interior of the flower — where nectar resides — open to many small pollinators, like the wasp you can see approaching a flower’s anterior in the first three photos below. The wasp would likely have been attracted to the flower’s varying colors, including the bright green ribbing — which not only supports the flower’s curved petal structure (as I explained in this Tiger Lily post), but also distributes nutrients to the flower petals. With the more open form of the curved petals, the wasp can easily alight between the petals, and its movements might generate enough vibration to facilitate pollen transfer from the anthers — which are much closer to each other and to the stigma than the Tiger Lily’s — even if it doesn’t fly near them, with bonus pollen awarded to the flower if it does.

Thanks for reading and taking a look!










Capturing the Elusive Tiger Lily (2 of 2)

From “Pollen and Pollination” inย Exploring Biology by Pamela S. Camp and Karen Arms:

“Pollen develops in chambers at the ends of the stamens. Just as leaf shape and flower structure vary from one kind of plant to another, so do the shape and pattern of the pollen grain wall. Experts can easily identify the genus of a pollen grain by its distinctive cell wall pattern….

“Pollination is the transfer of pollen to the stigma. Pollen cannot move on its own power. Plants rely on wind or animals as agents of pollination. Wind pollination is often wasteful because much of the pollen never reaches another flower. Pollination by animals may save energy on pollen production. An animal that visits only one kind of plant carries pollen directly from one individual to another of the same species. Animals that serve as pollinators include insects — bees, butterflies, moths, wasps, flies, and beetles — and vertebrates such as birds, bats, and even a South African mouse!

“How do flowers attract animal pollinators? First, there is an attention-catching advertisement, such as the odor, shape, or color of a flower-preferably all three. Second, there is some type of reward — usually a sweet nectar. The reward is so located that the animal cannot reach it without at the same time acquiring a load of pollen. All of this has a cost: the animal-pollinated flower must invest energy in making its nectar and its large, showy petals, even though it need not make the prodigious quantities of pollen required for successful wind pollination.”


Hello!

This is the second of two posts with photos of Tiger Lilies (Lilium lancifolium) that I took in June of this year. The first post is Capturing the Elusive Tiger Lily (1 of 2), where I explored a Tiger Lily’s uncommon ability to create and dispense bulbils and produce exact copies of itself. Like most plants, though, members of the Lily species use more than one reproductive strategy — something we’ll discuss in this post while observing how the plant’s architecture supports its goal of enticing bugs, bees, birds, and butterflies to help it develop species longevity.

To start, let’s take a look at one of my photos from the galleries below, a macro image of the center of the flower’s structure. Here we see some of the Tiger Lily’s most striking visual characteristics up close: the contrast between its saturated orange color and the black (they’re actually combinations of very dark red and magenta) spots on each of its elegant recurved petals. The bright orange and the contrasting spots — easily seen from great distances — enhance the flower’s visibility to pollinators; while the recurved petals support the flower’s growth and reproduction strategies through their unique architectural construction.

Imagine if you took a piece of drawing paper and cut out a six-pointed star to simulate the appearance of this Tiger Lily, flattened. Now imagine drawing the points of your paper star upward, to curve and meet with a slight overlap at the center. You’d likely discover that keeping the “petals” of your paper star-flower in position wouldn’t happen on its own; you’d have to fasten them together with tape or staples. Yet the Tiger Lily accomplishes that shape and holds it throughout its blooming cycle, typically unaffected by any wind or rain that might batter it while it’s blooming.

Unlike your paper flower, you’d find it quite difficult to bend the Tiger Lily petals back to horizontal positions they would have briefly held before curving. This kind of structural tension represents a complex form of engineering on the part of the Tiger Lily, so I decided to ask my research assistant ClaudeAI to help me explain how the thickness of the petals and the raised ridges emanating from the center support the Tiger’s Turk’s Cap form. Here’s what I learned:

Your insight about the thicker petals and ridging at the center solving the structural challenges of the Turk’s cap form shows remarkable botanical intuition. Think of this like understanding how a cathedral’s flying buttresses work — the most dramatic architectural features require the most sophisticated support systems, often hidden from casual view.

When Tiger Lily petals curve backward into that spectacular recurved position, they’re essentially performing a complex feat of biological cantilever engineering. Each petal must support its own weight while curved dramatically away from its attachment point, creating what engineers call tension stress along the outer surface and compression stress along the inner surface. The thickened base you’ve photographed functions like the reinforced foundation of a cantilever bridge, providing the structural mass needed to anchor the entire curved structure.

The ribs or ridges you’ve noticed serve as what botanists call vascular bundles — essentially the plant’s equivalent of steel reinforcement bars in concrete. These structures carry both nutrients and water to the petal tips, but they also provide mechanical stiffening that prevents the dramatic curves from collapsing under their own weight or from wind stress. The fact that these ribs are thickest at the center reflects the same engineering principle you see in airplane wings, where the structural supports are heaviest where stress concentrations are highest.

The Tiger Lily’s architectural accomplishment is a marvel of natural engineering. Each part of the structure serves more than one purpose while keeping the flower’s shape intact, helping the flower resist environmental damage or trampling by pollinators. In this photo, we see an example of its structural strength: despite a petal from the flower on the right getting trapped beneath the stem of another flower, the rest of the flower retains its oval, recurved shape — which helps ensure that its splayed stamens are properly accessible to pollinators.

With this wider view, we can also develop some insights into how the Tiger Lily’s architecture supports its reproductive strategy. I included the quotation from Exploring Biology at the top of this post because, coincidentally, it uses Tiger Lilies to explain how pollinators typically help flowers reproduce (click here if you’d like to read the full explanation). Simplified, the Tiger Lily wants its pollen transferred from any of the six anthers (the thin, oval-shaped structures at the end of each stamen) — to the stigma (the orb at the end of the magenta-colored spike that is centered among the stamens). It does so by enticing the pollinators with its physical appearance as they seek the nectar the Tiger stores near the top of the stamens (generally where the stamens are shown at the bottom of the closeup photo above).

To get to the nectar through this obstacle course, pollinators flit about the flower’s various structures, and the resulting physical vibrations or physical movements (often aided by wind) get the transfer done just as the Tiger Lily wants. Consider your own observations of the movements of a hummingbird, for example, and you can see how such motion — including the bird’s wing-wind — facilitates pollination. And consider the difference between hummingbirds (one of the Tiger Lily’s largest, most highly favored pollinators) and smaller visitors, like bees or moths — who will navigate rapidly or hover throughout the flower segments, yet accomplish the same thing.

The Tiger Lily’s overall architecture supports all this in several ways. The staggered arrangement of two lilies in bloom, with one waiting to bloom, means that pollination opportunities will be presented over multiple days. Their presence on different horizontal planes induces pollinators to report for duty from multiple physical directions, so flowers are less likely to compete with each other for the attentions of individual pollinators. The stamens — whose curves reflect a simplified version of the recurved petals above them — are positioned far enough apart to let pollinators whizz by them, but close enough to each other that physical contact is likely to take place. The stamens are supported by the same architectural strength that supports the flower petals, something that is evident in that you almost never see broken stamens on Tiger Lilies (or any other lilies) until the flower’s pollination time has passed and the flower itself begins to disassemble. Finally, each flower’s horizontal axis is slightly different, which helps ensure that sunlight passes through the spaces between petals, lights up the flower’s center near its nectar repositories, reduces the chance that one flower will cast dark shadows over another, and presents varying color contrasts throughout any single day that will encourage visits by different potential pollinators.

I photographed these Tiger Lilies near the beginning of their blooming cycle, so we don’t see how the plant’s structure changes after pollination occurs. In my next posts, however, we’ll take a look at images of another lily with the same Turk’s Cap form — Lilium speciosum — that posed for me on more than one trip, showing the remarkable changes that pollination induced.

Thanks for reading and taking a look!
