Lady Banks’ Rose, Spring 2025 (2 of 2) / Notes on Visualizing Botany

From Flora: An illustrated History of the Garden Flower by Brent Elliott:

“In 1685, Chinese ports were officially opened to ships of all nationalities. Even then, customs regulations were so strict that foreign trade was effectively limited to Macao and Canton. Nonetheless, some Chinese plants began to arrive in Europe. Chinese chrysanthemums appeared briefly in the Netherlands in the 1680s, but soon disappeared from cultivation, while an Oriental hibiscus flowered at the Chelsea Physic Garden in the first decade of the eighteenth century. The hibiscus was introduced by the East India Company doctor James Cunningham, yet most early eighteenth-century introductions came from unidentified sources. Although Chinese plants had limited impact in Europe at the time, the accounts of Chinese gardens by Jesuit missionaries led to a fashion for Chinese-style effects in European landscapes.

“The early nineteenth century saw sporadic but enthusiastic attempts to introduce Chinese garden plants, importing to Europe the results of China’s centuries-old traditions of plant breeding. Chrysanthemums, China asters, camellias, peonies (especially tree peonies or moutans), and roses, all excited attention in Britain and Europe. Most were introduced by horticulturally minded sea captains. Sir Joseph Banks, the Director of the Royal Gardens at Kew, planted the first tree peony there in 1790. Sir Abraham Hume of Wormleybury in Hertfordshire was active in distributing peonies and chrysanthemums. Two founders of the Horticultural Society, the amateur gardener and collector Charles Francis Greville and William Townsend Aiton, the superintendent of Kew, helped distribute plants, the latter from specimens received at Kew. Among the results, in the first decade of the nineteenth century, were hydrangeas and tiger lilies. In 1818, John Reeves, a tea inspector at Canton, began to send plants to the Horticultural Society, among them some of the first wisterias….

“In the 1820s the Society sent two collectors to China: the first, John Potts, returned with seed of
Primula sinensis; the second, John Damper Parks, was sent with specific instructions to look for the yellow form of Rosa banksiae.”


Hello!

This is the second of two posts featuring photographs of a rambunctious Lady Banks’ Rose from Oakland Cemetery. The first post is Lady Banks’ Rose, Spring 2025 (1 of 2).

As I’ve mentioned more than once here, I sometimes experiment with several AI tools to help me learn more about the plants and flowers I photograph. For me, it’s a shortcut to merge what I’ve learned about photography with what I continue learning about botany. And at this point, I’ve used them enough to recognize — despite appropriate misgivings about their future impact (as seen in aggressive marketing mixed with technological utopianism) — how they’ve improved over the past couple of years in areas that are relevant to me: photography and botany. I interact with ClaudeAI the most because in my experience it excels at explaining things in a botanical or historical context, and clarifying any questions I have or resolving what appear to be contradictions in its explanations.

Two years ago, I couldn’t get any of the AI tools to accurately identify flowers that are perhaps universally known to human beings. In other words, they couldn’t tell the difference (for example) between a daffodil and a tulip, despite each of those having easily recognized and distinct shapes. Fast forward a bit, and now Claude can tell me what’s in a photograph in detail — from the colors in the image, to the subject, to the shapes and structures in the background — and can usually identify a plant from one or two photographs, especially if the photographs contain other elements besides its flowers, like the stems, leaves, and surroundings where it’s growing.

At the same time, the tool understands characteristics of photography in surprising ways. It’s able to analyze a photograph, describe its compositional strengths and weaknesses using photographic concepts, and suggest improvements. I’ve used that capability to get recommendations about how to create better separation between subject and background in a photograph, how to most efficiently mask parts of a complex image before making adjustments, and how to use features in Lightroom in ways I hadn’t thought about before with step-by-step instructions. I’ve even uploaded two versions of the same image — one before I’d made any changes to it, and my final version — and asked Claude to explain the differences, which it did in terms of specific Lightroom steps I likely used to create the final version. And in one of the most useful conversations I had with it, Claude described how Lightroom’s Generative Remove Tool (which is also a form of AI) works, and how to influence its recognition of what’s in a photo so it provides better results when, say, I remove some dead flowers from a photograph of an iris and want them replaced with elements that look like nearby stems or leaves.

So to me this means I can do something like this: I can upload a few of my Lady Banks’ Rose photographs and ask for some observations both on the photographic characteristics of the image, and the botanical significance of what I photographed.

Using photos from this series, then, I inquired about three things: Rosa banksiae’s overall growth patterns; the arrangement of both opened and unopened flowers next to each other; and the red edging that appears on many of the leaves (most visible in the fourth, fifth, and sixth images below).

Here’s what Claude told me (that is, here’s what I learned):

Your photographic observations reveal some fascinating botanical principles at work, and I think exploring these visual elements will deepen your understanding of how this ancient rose species has evolved to thrive in its environment.

Let’s start with those dramatic architectural forms you’re capturing. When you photograph branches that seem to hang in midair or run in seemingly impossible directions, you’re documenting what botanists call “thigmomorphogenesis” — the way plants respond to physical touch and mechanical stress. Think of Rosa banksiae as nature’s sculptor, constantly feeling its way through three-dimensional space. Each branch that encounters a tree trunk, stone monument, or even another branch of itself will change its growth direction, creating unexpected angles and curves that make your photographs so dynamic.

The arched sweep pattern connects to something even more fundamental about how this rose conquers space. Picture the plant as following what we might call a “fountain strategy.” The main stems grow upward with vigor, but as they extend and become heavier with foliage and flowers, gravity naturally pulls them into those graceful arcs. This isn’t random — it’s an evolutionary solution that allows the plant to cover maximum territory while maintaining structural integrity.

Now, let’s examine those clusters of flowers mixed with unopened buds pointing skyward. This arrangement demonstrates what botanists call “determinate flowering” combined with “sequential bloom timing.” Think of each flower cluster as a carefully orchestrated performance where not all the actors appear on stage simultaneously. The buds pointing upward are positioned to catch maximum sunlight as they develop, while the opened flowers below them have already completed their primary function of attracting pollinators. This staggered timing extends the overall flowering period and ensures that some flowers are always at peak attractiveness to insects, even within a single cluster.

The red-edged leaves you’ve noticed represent one of the most overlooked aspects of Rosa banksiae’s botanical sophistication. That thin red margin isn’t merely decorative — it’s a sophisticated adaptation that tells us several important things about the plant’s physiology. The red pigmentation comes from anthocyanins, the same compounds that create red autumn leaves. In Rosa banksiae, these pigments serve as a natural sunscreen, protecting the delicate leaf edges from damage while also potentially deterring certain leaf-eating insects.

Think about what this means photographically and botanically. Those red edges create visual definition that helps each individual leaflet stand out against complex backgrounds. But from the plant’s perspective, this edge pigmentation represents millions of years of evolutionary fine-tuning. The red compounds can also act as antioxidants, helping the plant manage the chemical stress of photosynthesis in bright sunlight.

Here’s a mental exercise that might enhance your photography: next time you’re capturing the plant, try to think like the rose itself. Where would you position a branch to capture maximum sunlight while avoiding competition with neighboring growth? How would you arrange your flower clusters to attract pollinators most efficiently? When you start seeing the plant as an active participant in shaping its own form rather than a passive subject, you might discover new angles and compositions that reveal the intelligence built into its growth patterns.

The combination of these elements — the space-conquering architecture, the strategic flower timing, and the protective leaf margins — creates what we might call the “visual vocabulary” of Rosa banksiae. Each photograph you take is essentially documenting a conversation between the plant’s genetic programming and its immediate environment, written in the language of form, color, and spatial relationships.

If you read all that (you did, didn’t you?), you can likely see what I’m talking about. I didn’t just get a description of the characteristics of a Lady Banks’ Rose; I got them in a wider context of my own observations from photographs I’d taken, which the AI’s response blends into a discussion of the plant’s botany by examining my photographs, then creating a bridge between photography and botany. And the idea of “thinking like the plant itself, seeing the plant as an active participant in shaping its own form rather than a passive subject” is something I’ve probably done without realizing it; but intentionally composing a photograph to reflect both its visual interest and its botanical characteristics is something I can expand on. Instead of just considering how it looks, I would consider how its appearance demonstrates its behaviors, its evolutionary strategies, and how it has adapted to its environment — and how to capture that when taking a shot.

Coincidentally (or possibly not!), I’ve been watching a fascinating documentary about plants called The Green Planet (2022). Yet another excellent David Attenborough production, this five-part documentary takes a similar approach to that suggested by Claude: it “flips the script” to show plants as active directors of their own behaviors as they engage with their environments. Attenborough describes it as filming plants, over time, in ways similar to filming animals for other nature documentaries. If you’re interested in plants at all, this documentary is worth watching (I’m on my second viewing), and here are a few sections I found compelling to whet your appetite:

  • The first episode — “Tropical Worlds” — shows how vines use their tendrils to latch onto other plants, push them out of the way, and pull themselves upward toward the sun. If you have any vines in your garden, I think you’ll find the video representation of their movement quite compelling.
  • Episode 2 — “Water Worlds” — has a segment about giant water lilies (Victoria boliviana or Victoria amazonica) that send a jagged spike from beneath the water to the surface. The spike (which reminded me of a morning star or flail weapon) then rotates in the movement of water and wind in increasingly larger circles, to clear away other plants and make room for the water lily to come — which will need a lot of open space because it’s a giant!
  • The same episode describes how a carnivorous Bladderwort (Utricularia) creates small bladders beneath the water’s surface, that are triggered upon being touched by tiny prey, after which they snap open and vacuum the prey into the bladder to consume it.
  • Episode 3 — “Seasonal Worlds” — includes a vignette that shows how nettles and brambles (which have thorns or hooks), and climbing vines like hops, appear in sequence as the first plants to fill out wild landscapes in spring, using their various “climbing appendages” to make their way through other plants and capture light, before large shrubs and trees produce leaves that cover them in shade. It also includes a segment on the parasitic dodder (Cuscuta), a tiny-leafed vine that attaches itself to other plants, punctures their stems and leaves, and sucks nutrients from the plants it attaches to. “Vampire vine” is sometimes used to describe this plant; to learn about how it works, see Scientists Find a Gene That Enables a Plant to Become a Vampire.
  • Also in this episode are examples of unusual relationships between plants and insects. The Hammer Orchid (Drakaea) produces no nectar so is incapable of summoning insects the traditional way for pollination. Instead, it produces a flower that resembles a female thynnid wasp, thereby attracting the male wasp of this single, specific species to have its way with the orchid and scatter pollen. This section of the Wikipedia article about Drakaea describes how that happens. Not to be outdone by Drakaea’s enticing escapades, the Silver Arrowreed (Ceratocaryum argenteum) produces and flings seeds that match the size, shape, color, and odor of antelope dung — which are gathered and buried by dung beetles (who have a preference for antelope droppings) to ensure the plants’ offspring germinate.

These are just a few highlights, but you can probably see — given my so-far six-year project of botanical photography — why I like this series. And each episode ends with about ten minutes explaining the techniques behind the videography, how it was filmed in part on-location and in part by recreating those locations in studios in the United Kingdom. Imagine, if you will, the complex effort required to replicate giant water lilies growing in a pond, in a studio. That’s a lot more complicated than my photography shoots at Oakland Cemetery — but I’ll bet it’s just as much fun!

Thanks for reading and taking a look!











Lady Banks’ Rose, Spring 2025 (1 of 2)

From “Banksianae Section” in History of the Rose by Roy E. Shepherd:

“Unlike that of many roses that have been in cultivation for many years, the early history of R. Banksiae is comparatively easy to trace. Historians agree on who first discovered the various forms, where they were first found, and the dates of their introduction into Europe. The lone difference of opinion exists as to when and by whom the single form, variety normalis, was first brought to Europe. Most botanists believe that [Albert] Regel discovered it in China a year or two previous to 1877, the date of his published description of it. Later, in 1884, Pierre Delavay sent a wild plant from Yunnan — presumably to Paris. The story persists, however, that it was grown in Scotland as early as 1796. If this is true, it was brought there by Robert Drummond, who accompanied his brother, Admiral Drummond, on a cruise in the China seas and returned with many plants which he planted in his gardens at Strathay, Scotland. As the plant alleged to be R. Banksiae was not able to withstand the rigors of a Scottish winter, it froze to the ground each year, therefore did not bloom and was thought to be of such little value that it was forgotten. However, the rose persisted, and in 1909 plants from cuttings given to E. H. Woodall produced their first single white bloom….

William Kerr, one of the first professional plant collectors, is credited with the discovery of the first double white…. In 1803, the Royal Society at Kew sent him to China to search for interesting plants of that country. The Chinese government placed very definite limitations on the area he was permitted to explore, and most of his discoveries were made in gardens in or near Canton. One of these was the Double White Lady Banks Rose, which was brought to England in an East India Company ship in 1807 and planted at Kew. The botanist Robert Brown is said to have named it the Lady Banks Rose in honor of the wife of his friend, Sir Joseph Banks, who had given considerable financial aid to the Kerr expedition….

“The major characteristics of all members of this group are very similar, the differences occurring only in petalage and color of blossoms and fragrance. All are trailing or climbing with distinctive 3-or 5-foliolate leaves that are lustrous on both surfaces. Thorns are few and scattered, or they may be entirely lacking. The blossoms rarely exceed 1 inch in diameter and are produced in large close umbels rather early in the season….

“In China where these roses are known as ‘Mu-hsiang’ the bark of the roots is collected and used for dyeing fish nets. It is claimed that this dye not only strengthens the net but also makes it invisible to the fish.”


Hello!

I’ve photographed this rose (officially, Rosa banksiae) before (see Lady Banks’ Rose (and Rose Mania) from 2023, and Lady Banks’ Rose (1 of 2) or Lady Banks’ Rose (2 of 2) from last year) — but since I once again found it in bloom when I was out hunting for daffodils in March and early April, I couldn’t resist aiming the camera towards it one more time (and probably not the last time!). Given its early (and relatively short) blooming period, it’s always a surprise to come across it among those flowers and trees that bloom first to mark spring’s arrival, where it sprays a range of bright yellow and soft orange colors in the air while much of the surrounding landscape is still filling in.

The first few photographs below show the span of this shrubby vine, whose breadth seems to have expanded every time I take its pictures. That it is both a vine and shrub makes it fun to photograph by starting with wider angles, then zooming in to clusters of mounding flowers, or strands that hang in midair, or individual blooms that seem to defy gravity by pointing toward the sky. The entire exuberant structure extends from a handful of stems or trunks rising from the ground and stretches many feet from there, with some flowers standing straight up on shorter, stiffer stems and others curving over the shrub’s own branches or any other structure nearby. One could spend a couple of hours just admiring it through the camera lens, and one did!

Thanks for taking a look!










Some Perfect Roses (2 of 2)

From “Rose Family (Rosaceae)” in Look at a Flower  by Anne Ophelia Dowden:

“This large family is found in all parts of the world, but especially in the northern temperate regions. It varies so much that some botanists think it should be split up into several
families.

“Roses are probably the best known and best loved of all garden flowers. But, though they have given their name to the family, they form only a very small part of it. Much more important to man are the fruit-bearing trees: apple, pear, cherry, plum, peach; and the berry-covered vines: strawberry, black-berry, raspberry. Almond fruits look much like apricots, but their seed is the nut we eat. Rose fruits (hips) are edible and were used in England during World War II as a valuable source of vitamin C.

“Medicines are derived from a number of the plants in this family: almond, wild-cherry, peach, blackberry. The leaves of burnet are a delicate addition to salads. And the wood of some trees — cherry, apple — is valuable for furniture and engraving.

“Our gardens and countrysides are full of beautiful members of the family…”

From “The Round” by Stanley Kunitz in Heart of the Flower: Poems for the Sensuous Gardener by Sondra Zeidenstein:

Light splashed this morning
on the shell-pink anemones
swaying on their tall stems;
down blue-spiked veronica
light flowed in rivulets
over the humps of the honeybees…


this morning I saw light kiss
the silk of the roses
in their second flowering,
my late bloomers
flushed with their brandy.
A curious gladness shook me….

Hello!

This is the second of two posts featuring a variety of early summer roses from Oakland Cemetery’s Gardens. The first post is Some Perfect Roses (1 of 2). For the photos in this post, I zoomed in for a close look at some of the details of individual flowers, filling the frames with rose petals and buds.

I was recently amused to learn that what we call rose “thorns” are technically not thorns at all, but the botanically correct term is “prickles” — because there is a scientific difference between thorns, spines, and prickles, described in some detail in the article How Did a Rose Get Its Prickles? Well, maybe so, but rewriting the famous Poison song to Every Rose Has Its Prickles doesn’t quite work, does it?

Thanks for taking a look!








Some Perfect Roses (1 of 2)

From Hybrid: The History and Science of Plant Breeding by Noel Kingsbury:

“Roses are the favorite flower of the Christian and the Muslim worlds: varying hugely in color (but famously never blue), shape, and scent, and are loaded with cultural significance and symbolism. The ancestral rose, Rosa gallica, may have been pink, but it threw up genetic combinations for red forms early and was stable enough to be still very important in rose breeding. It dominated the gene pool of the rose until the nineteenth century….

“‘Old’ roses flower only once every year, in early summer. The Chinese
R. chinensis, however, carries genes for repeat flowering, so its introduction brought about a revolution in rose breeding. However, the repeat flowering habit was recessive, which limited the breeding possibilities in the early nineteenth century, in addition to which hybrids between this species and others were usually sterile….

“[A] fertile cross was achieved in France in the 1830s and gave rise to the hybrid perpetual group. As well as flowering only once, ‘old’ roses were also only available on a spectrum from crimson to white. It was not until the 1820s that the first yellow rose species were introduced to Europe and the United States, but it took many decades before successful hybrids were created….

“The French
Joseph Pernet-Ducher (1859- 1928), regarded by many as the greatest rose breeder of all time, created the first yellow roses; his hybrid tea class ‘Soleil d’Or’ of 1900 was the first ‘real’ yellow, as opposed to the wishy-washy yellows of previous attempts….

“Importations of roses from China were frequent during the nineteenth century; often they arrived on cargo ships bearing tea, which led to the roses which were bred from them to be dubbed ‘tea’ roses. Many had a touch of yellow, were well scented, and, unlike the flat blooms of traditional European roses, had a slight point in the center of the flower. This point gave each flower a very different character to what people were used to — and made the flower look particularly attractive just as it was about to burst out — a bud that spoke of promise as well as beauty. “

From “One Perfect Rose” by Dorothy Parker in The RHS Book of Garden Verse by the Royal Horticultural Society:

A single flow’r he sent me, since we met.
     All tenderly his messenger he chose;
Deep-hearted, pure, with scented dew still wet —
     One perfect rose.

I knew the language of the floweret;
     ‘My fragile leaves’, it said, ‘his heart enclose.’
Love long has taken for his amulet
     One perfect rose.

Why is it no one ever sent me yet
     One perfect limousine, do you suppose?
Ah no, it’s always just my luck to get
     One perfect rose.

Hello!

The roses featured in this post (and the next one) played a supporting role in one of my previous posts (see Orange and White Irises — and Creamsicles!), where I got them to pose as background color for the irises. You can see one of those irises in the first three images below, and get a sense of how many many-colored roses formed a border around them.

But with their long and complex cultural history, the roses deserved some attention of their own — so after finishing up my iris photography, I took their pictures too. They all may have been new plantings in this section of Oakland Cemetery’s Gardens, or I may have just passed them by or missed their blooming season in previous years — but they were a delight to see and the combinations of yellow, red, white, and orange colors were fun to photograph. Plantnet identified the roses in these photos with several possible variant names, including Austrian Copper Rose, Wichura’s Rose, Tea Rose, and French Rose — which probably reflects the color varieties as well as the varying flower structures you can see in the photos.

The quotation from Hybrid: The History and Science of Plant Breeding at the top of this post provides a widget of early rose breeding history, including mention of an “ancestral rose” called Rosa gallica from which most of our modern roses were hybridized and developed. Rosa gallica presents a simpler form than the roses in this post — typically with a single row of flower petals similar to a dog rose or even anemone flower — but its genetic characteristics made it possible to create variants with other colors, flower forms, and blooming frequencies. In The Rose: A True History, author Jennifer Potter describes this rose as “the foundation species from which most of our garden roses have evolved.”

Now you know a little about the origin story of roses!

Thanks for reading and taking a look!








Lady Banks’ Rose (2 of 2)

From “Roses of Nature: Origins of the Species” in The Rose: An Illustrated History by Peter Harkness:

“All the roses of the world in their glorious variety descend from wild roses. These naturally occurring species have been recorded in literature and folklore for centuries, but their origins stretch back further beyond written history. Indeed, the very earliest roses known to science are fossils….

“There are at least three different stories explaining how [
R. banksiae] came to Europe. One states that seed of R. banksiae alba-plena sown in Italy in 1869 germinated as R. banksiae normalis and was exhibited in Florence in 1874. Another story holds that the species was recorded in China in 1877 and came to Paris in 1884. There is also the tale that in 1796 a plant was taken from China to Megginch Castle in Scotland. It failed to flower due to a combination of unwise pruning and cold springs, but survived, and in 1905 cuttings were taken to the south of France where they proved to be R. banksiae normalis.

R. banksiae normalis bears sprays of simple white or yellowish white flowers, which appear in great profusion in early summer on stems that can extend 40 feet (13m) or more. The flowers carry the scent of violets, and the effect is such that in its native China it is known as the ‘wood smoke’ rose, or ‘Mu-Hsiang’. Its preferred native habitats are valleys and rocky places near a source of water, and in Yunnan it is grown around paddy fields to help stabilise banks and keep livestock away….

“This ‘aristocratic and altogether splendid rose’ (to quote Graham Thomas) proved rather tender for the British climate, but in 1799 it was sent to the President of the United States, Thomas Jefferson, who was a keen rose fancier. It was so well suited to the dry south-east states that it became a serious environmental problem there. In Bermuda, where it also suckers freely, it is known as ‘the fried egg’, and the Bermuda Rose Society has issued a special warning to its members: ‘Think twice before planting!!'”
