Iris Domestica Fireworks (2 of 2)

From “Blackberry Lily/Leopard Lily (Iris Domestica) in The Illustrated Guide to Nature by The National Georgraphic Society:

“The Blackberry Lily spreads wide its distinctly spotted tepals (look-alike petals and sepals) as if to draw attention to its short-lived beauty, as each blossom lasts only one day.

“A native of China, the Blackberry Lily has escaped cultivation to become widely established in North America. Showy flower sprays appear in the midst of fan-shaped clusters of long, narrow, flat, medium-green leaves. Pear-shaped seedpods form in late summer. When ripe, they split to reveal a cluster of shiny blackberry-like seeds, the source of the plant’s common name; the spots, of course, lend another name — Leopard Lily. A species of a different genus also goes by the name Leopard Lily; Lilium pardalinum, native to California, has somewhat similarly spotted tepals that curl. Its range does not overlap with that of Iris domestica.”

From “Belamcanda” in The Gardener’s Guide to Growing Irises by Geoff Stebbings:

“This genus is native to China, Japan and northern India. The plants look like iris, with fans of quite wide leaves. Given a moist, humus-rich soil they will grow outdoors in temperate zones and should survive most winters, but they are not long-lived plants. There is just one species, B. chinensis, which usually grows to 60cm (2ft) when in flower.

“The inner and outer petals are very similar except that the inner ones are slightly smaller, and the flowers open flat, facing upwards. The petals are orange, spotted with red at the base, and are attractive but not showy. This plant is called blackberry lily because the seed pods open to reveal shiny black seeds.”

Hello!

This is the second of two posts featuring Iris domestica from Oakland Cemetery’s gardens. The first post is Iris Domestica Fireworks (1 of 2).

Here’s one of the images from the galleries below, where you can see some of the unique features of Iris domestica that add to its photographic charm but also serve important botanical purposes. As the flowers age, the petals fold and twist in on each other, forming a tight spiral that retains much of the color from the underside of each petal. This change may occur within a few hours of blooming, as Iris domestica flowers often open and close within a single day.

Coincidentally, they share this trait with daylilies — and their aging process is another example of flower senescence, as I described in one of my previous posts, Red and Yellow Daylilies. This is a complex chemical and biological process, one that enables the plant to conserve energy and retain water, as the spiraled flowers will consume less energy and require less water. The plant can then redirect that energy and water toward the growth of other flowers and stems.

In the classic iris book The Genus Iris by William Rickatson Dykes, the author describes the process for Iris dichotoma, a closely-related iris that exhibits the same behaviors:

“This Iris probably produces more flowers on each stem than any other Iris. The stem is much branched and even the branches often issue in pairs at the same point. Moreover from each spathe as many as five or even more flowers are produced in succession. Each flower, unfortunately, lasts only a few hours and often only opens in the afternoon… However, such is the profusion of flowers that there are usually four or six to be found open at once on each plant.

“Another peculiarity of this Iris lies in the fact that it does not begin to bloom until about the middle of August and then continues in flower for about three weeks or a month. Each flower as it dies twists up in a curious spiral and often falls off together with the ovary between which and the pedicel there is an articulation.”

Sounds complicated, of course, but here we don’t worry too much about chemical and biological mechanisms we don’t (yet!) fully understand. You can click the links above for definitions of the three key botanical terms, if you like, but the process (somewhat speculatively) amounts to this:

The aging flower twists in a spiral, possibly to help the plant conserve water and energy. The position of the twisted spiral at the top of the seedpods helps protect the pods from insect or weather damage, until the pods themselves begin to dry out and open to reveal black seeds inside (the behavior that led to the common name “Blackberry Lily”). The seeds are then distributed by any of several seed dispersal methods, including gravity, wind, rain, and creatures like birds or passerby people.

All this enables the plant to make new plants — so I can take pictures of them again next year. Plants are both smart AND photogenically cooperative!

Iris Domestica Fireworks (1 of 2)

From “Perennials for Summer Bloom” in Sunbelt Gardening: Success in Hot-Weather Climates by Tom Peace:

“Blackberry lily (Belamcanda chinensis) is, despite its deceptive common name, actually a member of the iris family. Vigorous, healthy fans of leaves arise from a small rhizome that expands only slowly over time and grows to two feet tall before blooming….

“The valuable foliage is then embellished by open, branched flower stalks rising above the leaves, producing a succession of orange-and-red-spotted, six-petaled blooms. (Hybrids called candy lilies expand the color range to yellow and purples.)

“The effect is like slow-motion fireworks, but the show doesn’t stop there. Swollen seedpods develop through late summer and split open in fall to reveal berrylike clusters of shiny black seeds. These readily germinate the following spring, increasing the size of Belamcanda colonies.”

From “Blackberry Lily” in Lilies and Related Flowers by Brian Mathew, illustrations by Pierre-Joseph Redoute:

“This showy member of the iris family is very closely allied to the true irises and indeed will hybridize with Iris dichotoma to produce a remarkable range of intermediate offspring. Belamcanda chinensis is the only species in the genus. The flower, with its six equal perianth segments and three slender style branches, is in fact quite different in structure from that of an iris, in which the six perianth segment are separated into falls and standards and the style branches are flattened and petal-like. The fruits also are rather distinctive, with capsules opening to reveal large black seeds; hence the name Blackberry Lily used in some countries.

“Like Iris, Belamcanda produces a fan of flat leaves from a small rhizome and in summer sends up a branching flower stem from the centre of the leaf cluster. This stem can reach 2.5 metres in wild specimens, but it is usually much less than this in cultivation. Each flower is of rather short duration, but because there is a succession of them, quite a striking display is produced over a considerable period of time. Although individual plants are usually short-lived, seeds are freely produced and the young plants rapidly reach maturity. Belamcanda is a native of China, Japan, Taiwan and the Himalayan region….

“The root has been used to cure sore throats and fevers and is also recommended as an antidote to poisons, in particular the bite of a cobra.”

Hello!

I had never really thought of these flowers as “slow-motion fireworks” — as they’re described in the first quotation above — but, you know, the description fits. And it fairly well applies to my photos below of Iris domestica from Oakland Cemetery’s gardens, where these little delights tend to grow at the very outer edges of tree-shade, so pick up a lot of filtered sunlight or backlighting. The result is that they glow against dark backgrounds, and the camera does a nice job of capturing the flower petal highlights while keeping the colors and shapes of the stems and buds intact.

As is often the case with popular flowers, you can choose a common name for this one from a long list. Leopard Lily, Leopard Flower, or Blackberry Lily are frequently used, but you could also pick Candy Lily, Freckle Face, Butterfly Lily, or Fire Lily; or replace “lily” with “iris” and have a whole new set of names. They all reflect either the color pattern or shape of the flowers, or (for Blackberry Lily) the plant’s habit of producing fat seedpods that turn black late in the season. “Lily” has stuck as part of the plant’s moniker, though — as we all know, don’t we? — it’s actually an iris. Iris domestica is its proper current scientific name; but that’s a recent enough development in botanical history that the previous scientific name — Belamcanda chinensis — hangs around in a lot of botany or gardening books and other sources. I wrote about the name change history last year: see Iris Domestica, the Leopard Flower or Blackberry Lily (1 of 3) if you would like to read more about it.

With that previous set of photos, I also wrote about encountering these irises shortly after a long-duration high-wind thunderstorm had passed through the neighborhood, bending many of them to the ground. Some had obviously been broken or uprooted, with the flowers still intact, stems split like cut flowers in a vase. I wondered if they’d return this year, so was glad to find them — even as a less robust crop than I had seen previously. Then again, the presence of fewer flowers gave me a chance to capture singular stems and flowers against their shaded black or dark green backgrounds, so for The Photographer, that worked out nicely.

White and Purple Irises

From “Dalmatica and English Nurserymen” in Classic Irises and the Men and Women Who Created Them by Clarence Mahan:

“[Peter] Barr and his sons Peter Rudolph and William were leading breeders of irises. Beginning with the introduction of a reddish-violet iris named Garibaldi in 1873, the Barrs produced scores of new irises. These Barr irises were highly regarded in their day. Mention has already been made of the Pallida Dalmatica look-alike Princess Beatrice. A few of the other popular Barr varieties were brownish-yellow Bronze Beauty, light blue-violet Alice Barr, blue-violet Khedive, and yellow and red-violet ‘Robert Burns’….

“One of Peter Barr’s lasting contributions to the world of garden irises was the gift of a special vocabulary. Garden writer and iris hybridizer Sydney B. Mitchell explained how this came about in his book Iris for Every Garden:

“‘About 1873 Barr issued a descriptive list of his extensive collection [of irises], arranging the varieties in groups: aphylla (including forms of germanica), amoena (white standards and purple falls), neglecta (lavender standards and dark falls), pallida (lavender, light and dark blue, and rosy-toned purple selfs), squalens (forms with blended, often rather dull, combinations of smoky blue and gray or yellow and red), and variegata (clear yellow standards and falls either veined a dark red or nearly solid ox-blood color). Barr’s classification was adopted and continued in English and American lists into the nineteen-twenties. Even to this day such terms as ‘amoena’ and ‘variegata’ are applied to modern hybrids of these old color patterns.’

“The terms ‘amoena,’ ‘neglecta,’ and ‘variegata’ continue to be used by those who write and talk about irises in the 21st century. These words refer to the color patterns described by Barr and form an enduring element of iris argot. It is, after all, easier to say than an iris cultivar is a ‘neglecta’ than to say that it is a ‘violet or purple iris with standards that are lighter in color than its falls.”

Hello!

This is the last of my iris posts for 2024 — unless I come across some of the very late bloomers, like the Leopard Lily (Iris domestica), which I can often find in July. The galleries below show those I photographed with white or nearly white standards and contrasting shades of purple in their falls. Toward the middle, you will also see some that have a thin white border around the edges of the purple petals, providing an extra touch of pizazz.

Separate from any scientific or botanical names, descriptions of iris color schemes have their own names — such as amoena and neglecta — which are explained in the quotation at the top of the post. The term “amoena” refers to an iris with white standards and colored (in this case, purple) falls, and “neglecta” is more ambiguously used to describe an iris where the standards and falls show distinct variations (light and dark, typically) of the same color, such as blue, purple, or violet. If you would like to read about some of the other terms used to describe iris colors, see (with pictures!) Iris Flower Patterns from the National Gardening Association.

While I’d heard some of these terms before, I don’t think I realized that they were an important part of understanding iris colors and talking or writing about them. Perhaps they fill the gap I’ve run into frequently, that it’s quite difficult to identify individual iris variants when you come across them in a garden or from photographs (unless you bought them at a garden center and kept their “my name is” tag). Assuming I photograph them again next year (and hunt down some new ones), I think I may try to separate them by these “official” color categories, just for the sake of learning how to apply them to my discoveries.

Gold Standards and Purple Falls

From “Iris” in The English Flower Garden by William Robinson:

“The Iris is one of the oldest of our garden flowers, in many forms too, but… it has come to us in greater novelty and beauty in recent years….

“The old Irises of our gardens are usually of the Germanica class; there is much variety among these groups, and they are very hardy and precious, and excellent for the adornment of gardens and even walls and thatched roofs, as we see in France, the Iris of this great group having a valuable power of thriving on such surfaces as well as on good soil.

“There is a group of waterside and water-loving Iris, much less seen in our gardens than the above, and some of them not yet come to us, but of great value. They are allied to the common yellow Iris of our watercourses, but are taller and richer in colour, the golden Iris (aurea), Monnieri, and ochroleuca being the best known so far, and very free, hardy, and beautiful plants they are, thriving, too, almost anywhere, but best in rich, moist soil….

“Then there are the brilliant purple and gold Iris reticulata and its allies, little bulbous Irises, for the spring garden, early and charming things, many beautiful; Irises that flower in winter and early spring, like the Algerian Iris; others happy in Britain on warm soils and warm corners, and some for the rock garden, like the crested Iris; and the many pretty forms of Iris pumila, of some of which edgings were made in old gardens….”

From “Variegata” in A Guide to Bearded Irises: Cultivating the Rainbow for Beginners and Enthusiasts by Kelly Norris:

“Variegata: An iris with yellow or near-yellow standards and darker falls of brown, red, or purple…

“Named for Iris variegata, this distinctive bicolor pattern is well represented in all six classes. In tall beardeds, cultivars include ‘Jurassic Park’ (Lauer 1995), ‘Mine’ (Headrick 2004), ‘Kathy Chilton’ (Kerr 2006), and ‘Born to Please’ (Rogers 2006)….

“The original pattern of yellow and brown still colors many irises in the MTB class but has probably tired just as many gardeners because of its limitations. I mean really, how many ways can you do yellow-brown-red in variation before it becomes a little trite? But jaded eyes aside, the variegata pattern makes great art in the landscape. The pattern plays off the familiar colors of yellow and purple in other plants, while jazzing up the color display more than something white or pink might.”

Hello!

The irises in this series have some similarities to those I posted previously as Brown Iris Mix — but I separated these out because they have a more distinct variations between the colors of the standards and the falls. Shades of gold and yellow-gold (rather than brown) dominate the standards, with purple tones filling the falls. Admittedly the distinction is a little ambiguous, but you may also see more stippling through these flower petals, suggesting that they are different variants than those in the earlier batch. There is a reasonably good chance that some or all these irises would be correctly identified as Iris variegata L. — often referred to as a “Hungarian Iris” in some parts of the world — but (as we sometimes say here) nobody knows for sure….

🙂

Until I found the first quotation about irises that I posted above, I was unaware of the practice in France of growing irises on rooftops. If you would like to see some examples — which may also include other European countries where irises are grown up high — click here. And if you’d like to see some additional irises in color schemes like those I photographed, they are Jurassic Park, Mine, Kathy Chilton, and Born to Please, from the second quotation above.

Tall Purple Irises

From “Iris Germanica” in Classic Irises and the Men and Women Who Created Them by Clarence Mahan:

“What is Iris germanica? Trying to define Iris germanica is not easy….

“Mathematician George Spencer Brown in Laws of Form asserts there are certain things of which one cannot speak, and he cites music as an example. You can try to describe a sonata, but you will never convey to another person the experience of actually hearing it. The same is true of an iris. An attempt can be made to describe it, but words will never be able to convey the experience of seeing the iris. Fortunately, you have seen Iris germanica.

“Even if you have not seen Iris germanica in the garden you have seen it in paintings or at least in reproductions of famous paintings. The purple irises in Van Gogh’s masterpiece Irises, which sold for the record-breaking price of $53.9 million in 1987, are Iris germanica.

“The irises that fill half the canvas of Claude Monet’s painting … The Artist’s Garden at Giverny, are Iris germanica. Monet’s impressionist style makes the identity of the irises difficult to discern but there is a key in the painting. The key is that wisteria is in bloom. Tall bearded iris species and cultivars bloom after wisteria flowers have drifted to the ground, but intermediate bearded irises, of which Iris germanica is the prototype, bloom earlier when the wisteria opens its buds.

“The typical form of Iris germanica has a 2-foot stem with two branches, one long and one short. It usually has four flowers, two at the terminal and one on each of the branches…. The flowers of different forms of Iris germanica come in various shades of violet but there are also white forms. The most common form has blue-violet standards and red-violet falls…. It is one of the hardiest of all irises. “

From “The Maid’s Thought” in The Selected Poetry of Robinson Jeffers by Robinson Jeffers:

Why listen, even the water is sobbing for something.
The west wind is dead, the waves
Forget to hate the cliff, in the upland canyons
Whole hillsides burst aglow
With golden broom. Dear how it rained last month,
And every pool was rimmed
With sulphury pollen dust of the wakening pines.
Now tall and slender suddenly
The stalks of purple iris blaze by the brooks….

Hello!

As you can tell from some of the photos below — especially the first five — these purple irises were among the tallest I photographed at Oakland Cemetery’s gardens this year, rivaling the height of some of the black irises I posted previously (see Black Iris Variations and Observations). They posed so I’d capture their height and could sweep in their background surroundings — and I liked the contrast between the purple irises and the fields of yellow flowers behind them. Those flowers — most likely a variety of spurge, probably Euphorbia polychroma, or Cushion spurge — were plentiful earlier this summer, and have since reverted to their more flowerless state, still providing a fine green blanket covering large areas of the gardens.
