Iris japonica (1 of 2) / Notes on Image Reconstruction

From “Iris Japonica” in The World of Irises by The American Iris Society, edited by Bee Warburton and Melba Hamblen:

“The much frilled and fringed flowers of Iris japonica lie almost flat and are 8-10 cm (3-4 inches) in diameter. The multibranched stalks, up to 60 cm (2 feet) in height, carry as many as 24-30 blossoms, two to each spathe. Generally four to six are open on each stalk, but when plants are well grown there may be many more. The pale lavender flowers have finely traced orange markings on their falls consisting of three slight ridges. The margins appear on a white ground outlined with splashy dots of deeper lavender shade. Smaller orange dots are contained within this area. The lavender style arms are finely fimbriated above the lip….

Iris japonica is a native of moist woods and grows best outdoors in cool, frost-free conditions…. Since it blooms in early spring, early to mid-March in climates where temperatures seldom go below 3 degrees C (26 degrees F) and freezes are rare, it enhances the azalea and camellia garden….

“Because of their shallow root growth, some kind of mulch is desirable at all times except under circumstances of excessive heat and moisture. New plants emerge some distance from the main rhizome… traveling on the surface of the soil. The damp mulch provides anchorage for these proliferations and encourages their rooting….

“These irises have no genuine dormant period since the foliage remains evergreen the year round.”

From “Japonicas and Hybrids” in Iris for Every Garden by Sydney B. Mitchell:

Iris japonica, sometimes also called I. fimbriata, is the most distinctive and beautiful of the crested irises. From fans of thin, bright evergreen foliage it sends up two-foot widely branched stems which bear over several weeks a succession of somewhat fugitive but lovely pale lavender flowers, fringed, and with orange crests. A single stem will bear dozens of blooms, so light and airy and so like orchids that this particular species is often referred to as the ‘orchid’ iris….

“Japonica is not in the least demanding as to soil, though its preferences are for one that is not too heavy and that contains humus and leaf mold. In contrast with almost all other irises, it succeeds far better in considerable shade than in sunlight and often will be found growing luxuriantly in the dappled shade of overhanging trees. Unfortunately japonica cannot be grown outdoors in very cold climates, but all along the Pacific Coast and through the southern states it is well worth trying.”


Hello!

This is the first of two posts with photographs of Iris japonica from Oakland Cemetery, that I took on one of my early spring photoshoots. Iris japonica is known by several common names, including Japanese Iris, Fringed Iris, or Butterfly Flower. You might also find it called Shaga or Shaga Flower, “Shaga” being a translation of its Japanese name, one that was used in early horticultural trade before European botanists assigned it scientific names. Both the Butterfly Flower and Fringed Iris names connect to the flower’s visual appearance: Butterfly Flower has Chinese origins reflecting how its spread flower petals resemble butterfly wings; Fringed Iris descends from one of its earlier scientific names, Iris fimbriata, where the Latin word “fimbriata” referred to the distinctive fringed edges of the flower petals. In iris classifications, Iris japonica is included in a group of visually similar crested irises, more formally known as Lophiris.

While they’re members of the same family as upright irises like Iris germanica or other tall irises — the Iridaceae family — their growth pattern is much different. Iris japonica grows close to the ground, as an understory plant that I’ve often found surrounding the trunks of Oakland’s massive magnolia and oak trees. Their early spring bloom time under those trees means that the plants emerge above layers of discarded leaves from the prior autumn as well as built-up winter debris. The evergreen leaves are abundant and large compared to the sizes of individual flowers; and the flower stems push through the layers of natural mulch to bloom just a few inches above ground.

In my last two posts about Camellia japonica (see Camellia japonica (1 of 2) and Camellia japonica (2 of 2)), I mentioned that I photographed the Camellia plant because I wanted to take on the challenge of properly rendering the red and magenta color blending in the flower petals. I took these Iris japonica photos to pursue a different challenge: to see what I could do with their untidy backgrounds, which we tend to ignore when viewing the flowers in real life but dominate any photo featuring both the flowers and their surroundings.

Here’s one of the photos in this series as it came out of the camera, where the flowers look just fine but the rest is a mess — a visually disturbing mix of broken, cut, or winter-damaged leaves that overwhelm the image:

In the olden days of a few years ago, I would — and occasionally did — produce photos of these flowers by zooming in on only the flowers, hiding the backgrounds as much as possible, or converting them to black. Despite how tedious that was, converting them to black — which involved carefully detailed masking around the edges of flower petals — would create a presentable image of the flowers, but only the flowers and maybe a few stems and leaves. I used that black background technique often with different kinds of plants (see here), and my black background period taught me a lot about how to use Lightroom’s masking tools to emphasize the subjects in my photos. Its biggest drawback, however, was the loss of environmental and botanical context since the images isolated only the blooms and eliminated everything else.

When Adobe added Generative AI Remove to Lightroom in 2024, the capability was introduced as a “distraction removal” tool to get rid of spots or unwanted objects in an image. It indeed does that (and does it well), but for my nature photography, I’ve adopted it as a reconstruction tool that’s perfect for conditions like those present in these Iris japonica photos. I can use it to rebuild or reconstruct severely damaged leaves; or, as I’ve come to think of it: replace damaged elements with what might have been there, if the damage had not occurred.

Lightroom previously had (and still has) its traditional healing and cloning tools, which operate by replacing something you select with pixels from another section of the photo. That means, in effect, you could select something like the tip of a broken leaf and replace it with the tip of another leaf that wasn’t damaged. But that would only work if you could find a suitable match. Scroll back up to my sample photo and see if you can find structures, colors, or textures — which matter a lot with botanical photographs — that would match those with any single piece of damage you might want to eliminate. It would be like trying to assemble a puzzle from pieces out of several boxes: most of them just wouldn’t fit.

Like a lot of photo editing tools, the original healing and cloning tools did exactly what you told them to do. Their behavior was literal and restricted to the image you were working on, with no broader context. Generative Remove, on the other hand, isn’t restricted like that; it can draw on an enormous amount of information beyond what’s present in a single image. While I don’t have technical knowledge about exactly how Generative Remove does what it does, I can see — from experimenting with it — that it recognizes patterns in the colors, forms, and textures of botanical (and other) subjects. It may or may not know anything about Iris japonica specifically, but manages to take selections I make and suggest replacements that are aligned with the natural appearance of parts of the plants.

Equally important, I’ve learned that I can influence Generative Remove’s replacement suggestions. If I want to replace the flatly torn end of a leaf in this image with a properly pointy Iris japonica leaf, I can make a roughly triangular selection and the replacement will look more like the tip of an unbroken leaf. And if I make an angled or curved selection aligned with the directional flow of the leaves, the replacement will mimic those angles or curves. These then lead to a more complex form of influence: the sections of the image I reconstruct first help establish how Generative Remove “sees” the image as I continue the reconstruction work, which enhances the quality and effectiveness of its additional replacement suggestions. That led me to develop a specific reconstruction workflow: remove smaller defects first so that some of the leaves are restored early on, then proceed to those with less damage, then finish up with those that are the biggest messes of all.

In this image, for example, I’m about halfway through leaf reconstruction. I’ve finished fixing those on the right side of the flowers, which had less damage than those on the left; and those in the upper right corner now match the natural appearance of Iris japonica leaves when they’re fully intact. These patterns then become additional context that Generative Remove can use as I move to the more seriously damaged leaves on the left side of the photo…

… which, when completed, look like this, and show why I think of this reconstruction as “what might have been there, if the damage had not occurred.”

Here you can see the transition from the original image, to partial reconstruction, to the final reconstructed version — that final version including color adjustments to reflect the flowers’ subtle blend of blue, violet, and purple tones. Select the first photo to view the series in a slideshow, where it should be evident how well the tool (with two hours of my help!) has managed to generate a botanically accurate and naturally plausible background for the flowers.

That the final image doesn’t reproduce exactly what was present at Oakland when I took the photo isn’t, of course, the point. All images — whether drawn or painted, produced by a film camera and retouched in a darkroom, or captured and enhanced by a digital camera’s creative modes — are interpretations rather than precise representations. A tool like Generative Remove provides a way to approach image editing differently, because the tool infers what should occupy any area I select from what’s actually present in the surrounding scene. That makes it possible to render a composition as our human visual system and memory experienced it, where distracting elements like damaged leaves in the background are filtered out in favor of the subject that attracted our attention to begin with. And — unlike the hyper-realism that often surfaces in an image created by an image generator, or even one where the background is replaced — this kind of editing preserves fidelity to the experience of taking a photograph and recalling what we found significant when we did that.

That the Generative Remove tool’s behavior can be influenced is one of the most interesting things about using it for reconstruction like this. But it’s also very different from tools that do exactly what they’re told, as the influence isn’t obvious at first and the results it produces seem ambiguous or random until you repeatedly observe how your influence can work. I don’t tell the Remove tool what I want to do in words; instead, I have to make selections, see what results it produces, decide whether they fit visually and look natural, then use them or modify them — with those choices (and the accumulation of many choices) influencing what the tool does each time I make another selection.

The closest description I can come up with is that it’s like a picture-based dialogue between a human and a machine toward a creative goal. This ambiguity and uncertainty can feel uncomfortable at times, yet embracing it means that the nuanced responses produced by AI-based tools — photo editing tools or even language models like ChatGPT or Claude — are not necessarily mysterious, but are within realms we can understand if we step back from the kind of literal instructions and expectations we’re accustomed to, when interacting with these new technologies.

Iris domestica: From Summer to Fall (4 of 4)

From “The Flowery Land” in Gifts from the Gardens of China by Jane Kilpatrick:

“It was during the peace and prosperity of the Tang period (AD 618-907) that the Chinese people first really had the security and leisure to devote themselves to gardens and to the cultivation of an expanding range of ornamental plants. In addition to the peach and the apricot, several other flowering trees became popular, although this was probably as much due to their mythological attributes and practical uses, as to their flowers and handsome shapes….

“Shrubs seem to have been uncommon in gardens before the seventh century, although
Weigela florida was sometimes used as a hedge plant, but references to the beauty and flowering season of magnolias, daphnes and hibiscus indicate that these very attractive plants were being brought into cultivation by this time. Herbaceous peonies (Paeonia lactiflora) were already favourite ornamentals, as were annuals such as the Chinese Pink and the Chinese Aster (Dianthus chinensis and Callistephus chinensis); but many plants grown as ornamentals today, such as the Tiger Lily (Lilium lancifolium), the Leopard or Blackberry Lily (Belamcanda chinensis) and daylilies, were still principally grown for their medicinal rather than their decorative qualities.”

From “The Story of the Fire Lily” in Someone Cares: The Collected Poems of Helen Steiner Rice by Helen Steiner Rice:

The crackling flames rise skyward
as the waving grass is burned,
But from the fire on the veld
a great truth can be learned…
For the green and living hillside
becomes a funeral pyre
As all the grass across the veld
is swallowed by the fire…
What yesterday was living,
today is dead and still,
But soon a breathless miracle
takes place upon the hill…
For, from the blackened ruins
there arises life anew
And scarlet lilies lift their heads
where once the veld grass grew
And so again the mystery
of life and death is wrought,
And man can find assurance
in this soul-inspiring thought,
That from a bed of ashes
the fire lilies grew….


Hello!

This is the fourth of four posts with photos of Iris domestica, and the second post with photos of Iris domestica ‘Hello Yellow’. The previous posts are Iris domestica: From Summer to Fall (1 of 4), Iris domestica: From Summer to Fall (2 of 4), and Iris domestica: From Summer to Fall (3 of 4).

I took the photos in the galleries below at Oakland Cemetery on June 21 and July 17, so they show the plant’s transition from its primary blooming period to the second phase where it produces seed capsules. You can see this transition about halfway through the galleries, starting with the photographs of the capsules, which show how this cultivar maintains quite a few flowers even as it starts generating seeds. When I went back in October to photograph the blackberries Iris domestica typically produces that I showed in the first post, however, only the orange-spotted variety had blackberries; those of Hello Yellow had already been dispersed. Together these characteristics suggest that Hello Yellow may have a more condensed reproductive cycle — moving from flower to capsule, blackberry development, and seed dispersal over a shorter time frame — but that could also reflect different environmental conditions, or simply that Hello Yellow was new to Oakland this year and may still be establishing its own rhythms.

The two varieties’ overall growth pattern is also quite different. The first two photos below show a typical group of orange-spotted Iris domestica, which produces fewer plants in any given location that tend to be spread up to a foot apart. This more solitary arrangement may indicate that the plant has evolved to disperse over wider areas — something that’s closer to its wild or native origins — which I observe by finding these orange flowers scattered throughout Oakland. Hello Yellow, on the other hand — as shown in the second two photos — has been bred to produce plants that grow in compact masses: the number of flowers and leaves in any square foot of the garden leaves little space between them as each plant produces crowded clusters of flowers. While both plants will present opened and unopened flowers while they’re blooming, these photos illustrate how differently they’re arranged, from a handful of flowers on each orange Iris domestica stem to Hello Yellow having so many flowers per stem that it’s hard to count them individually.

Because of these distinct growth patterns, the orange Iris domestica appear throughout Oakland as transitional plants marking the boundaries of roadways and blending among other plants, where their bright orange flowers draw your eye toward them and their immediate surroundings. But as we can see from this photo, Hello Yellow, by contrast, produces densely packed leaves topped with bright yellow flowers that are visible from a long distance, making them integral components of a memorial scene:

These Hello Yellow cultivars are growing in one of the many raised sections of the cemetery, about three feet above the roadways that surround it (a very handy position for photographers), and constrained on all sides by a stone wall. When you face that particular plot, you first see the low, soft textures and colors of Lamb’s Ear, which allow shorter memorial markers to remain visible even as Hello Yellow consumes more territory but doesn’t displace the smaller plants. Hello Yellows grow abundantly behind the Lamb’s Ear bunches, where they come close to matching the height of taller gravestones, as well as those in the background, but don’t detract from them visually.

Arrangements like these are not accidental: it’s apparent from their visual characteristics that Oakland’s landscape designers chose these plants intentionally, to provide different visual layers to the scene as time passes and to blend these plants with the immovable parts of their surroundings — like the memorial stones and even the remains of an old tree trunk whose dark colors provide additional contrast for the scene. Given its origins in seventh-century China (as explained in the excerpt from Gifts from the Gardens of China above), Iris domestica (in all its forms) seems especially appropriate for historical garden settings like this, but we’ll have to wait until next year to see if Hello Yellow takes after its orange relative and ventures beyond its present borders.

Iris domestica: From Summer to Fall (3 of 4)

From “Belamcanda” in Perennial Gardening by Michael Ruggiero: 

“Both species in this genus (also called leopard flowers) are native to China and Japan. B. chinensis is becoming popular in this country as an ornamental, for its shiny blackberrylike fruits as much as for its orange-spotted flowers; once finished, the flowers twist up tightly….

B. flabellata ‘Hello Yellow’ is a wonderful smaller (10-inch) cultivar with the typical blackberrylike fruit….

“Both are fairly easy to grow and are unusual additions to summer and early fall flower borders. Group several plants together to get a telling display. Blackberry lily grows best in full sun positions, in well-drained, reasonably fertile soil…. Planting may be done in spring or fall, but newly planted stock should be protected with a winter mulch. Propagation is most satisfactory by seed sown in spring, either out of doors or indoors at about 70-80ยฐ F. Germination will take 2-4 weeks….

“Some gardeners prefer to divide the rhizomes in spring or early summer. Iris borer may attack the rhizomes with devastating effect; dig and destroy as soon as damage is seen; do not compost the foliage to prevent overwintering of borers. Leaf scorch causes an unsightly browning of the irislike leaves. Do not deadhead, or the attractive black glossy fruits will not form. Self-seeding is not a problem.”

From “Lodestone” in Of This World: New and Selected Poems 1966-2006 by Joseph Stroud:

I lie in a hammock in the slow hours
of a summer day, summer at last
in the high country, summer in the air,
in the light, in the poems I’m reading,
poems like deep jade pools of snowmelt
under a summer sun, poems like
whorls of agate. There’s a drift of pollen
through the forest, sifting through
the pines and cedars, a fine gold powder
drifting like the crushed ash of sunlight.
In the seep on the hillside the first
rein orchids appear, the night-blue larkspur,
leopard lilies….


Hello!

This is the third of four posts with photos of Iris domestica, where we’ll spend some time looking at one of its cultivars, whose appearance and growth patterns are quite different from the plants I shared in the first two posts, Iris domestica: From Summer to Fall (1 of 4) and Iris domestica: From Summer to Fall (2 of 4).

Since the origins of this cultivar’s name — Iris domestica ‘Hello Yellow’ — are hard to pin down, we can just enjoy the fact that the plant was given this happy little moniker. The excerpt I included at the top of this post — from the book Perennial Gardening by Michael Ruggiero, published in 1994 — refers to Leopard Lilies by their earlier name Belamcanda, calling the yellow cultivar Belamcanda flabellata ‘Hello Yellow’ and calling the more frequently planted orange cultivar Belamcanda chinensis. So we know that ‘Hello Yellow’ has been around for at least thirty years, before the two plants were subsequently determined to be variants of the same species and their names were changed to Iris domestica and Iris domestica ‘Hello Yellow’. The original Belamcanda names actually strike me as more precise than the newer ones — since Iris domestica could now be used to include both cultivars — but these things sometimes happen when plant names change over the years. Belamcanda flabellata ‘Hello Yellow’ even captures more of the yellow cultivar’s physical characteristics by not only including the color of the flowers, but also including its fan-shaped leaves — that’s what “flabellata” means — whose distinctive appearance you can observe in the first five photos in the galleries below.

In my first post in this series, I mentioned that Hello Yellow appeared to have been bred to eliminate the spots that had given rise to the plant’s “Leopard Lily” common name, a name that crossed the boundaries between plant life and animal life. Since then, I got to puzzling about that — as one does — which led me to wonder if there were cat-leopards that originally had spots but those spots had disappeared over generations and time. Researching that led me to this interesting article The Black Leopard Has Secret Spots, which describes how the ancestral remnants of spots on this cat’s sleek black coat can be revealed by photography, especially infrared photography.

If you look at the lead photo in that article, however, you can see that it doesn’t actually require infrared photography to reveal the hidden spots. Instead, the right lighting conditions — in that case, sunlight filtered through surrounding trees and shrubs — achieve a similar effect. With that in mind, I knew that I took some of my Hello Yellow photographs when the sun was behind clouds, which would have resulted in lighting a lot like that of the leopard photograph. Here, for example, is one of those photos…

… where you can find Hello Yellow’s spots if you look closely. Follow the petals of the frontmost flower from their edges to the center, and you’ll encounter what may look like bits of pollen, but these are actually spots whose color has been altered from Iris domestica’s original deep purple or black to a shade of yellow-orange that’s slightly darker than the rest of the petals. These color variations are only evident in filtered sunlight like this; you won’t see them in the photos that I took when the sun was out.

But there’s more! Here we compare Hello Yellow to the orange spotted cultivar and can see something else. Notice how spots are distributed among the flower petals on the orange blossoms, then take a look at those same sections of the petals on the yellow variant:

You will see, in this comparison, pale yellow circles and circular texture variations among Hello Yellow petals that are distributed in the same patterns as the dark spots on the orange flowers. These, too, are remnants of the plant’s original spotted appearance, where the plant’s colors have been altered through selective breeding to shift the overall petal color from orange to yellow, and simultaneously reduce the dark spots to shades of yellow. So, as it turns out, the common names Leopard Lily or Leopard flower still work for Hello Yellow after all!
