Zinnia Elegance (1 of 4)

 , , , , , , 2

From A History of Zinnias: Flower for the Ages by Eric Grissell:

“[Zinnias] are members of the composite or Asteraceae family of plants — imagine a sunflower — that represents a cluster of hundreds of individual tiny flowers growing upon a single platform called the receptacle. Therefore, and speaking technically, a zinnia or composite is not a flower but instead is a cluster of flowers, as its name suggests. In presenting a single sunflower to a favorite person, for example, it is most correct to exclaim ‘I have brought you a bunch of sunflowers,’ but this most likely won’t catch on.

“The small flowers that compose the ‘flower’ of the Elegant Zinnia and all its relatives represent two basic types: ray flowers and disk flowers. Ray flowers each bear a single colorful petal and often a seed at its base; in single flowers these petals are lined around the rim of the receptacle, producing the ‘sunrays’ as in a sunflower. Disk flowers have no petals and form the central cone of a zinnia. Whereas ray flowers are either sterile or female, disk flowers are both male and female, frequently appearing yellow or orange due to pollen of the male parts (anther/stamens), giving the center of a single composite flower its additional smidgen of color.”

From “Visitation” in North of Eden: New & Collected Poems by Rennie McQuilkin:

I’ve been anxious all morning,
have come outside to sit by the fall flowers,
shaggy orange and pink and yellow zinnias
grown tall for the occasion
beside the rough-hewn slats of a barn-red barn.
The day is warming after a touch of frost.
The zinnias have made it through

and have a caller
on orange-red, black-veined wings
rimmed with white dots and yellow oblongs.
The wings go from flower head to
head, landing, shutting, opening slowly,
then folding together like supplicant hands
palm to palm for the long deep drawing in,
and rising for delighted swags of dizzy flight
up and down the length of the barn
before lighting on another zinnia….

Hello!

As I mentioned in my most previous post (see Zinnias and Fritillaries), I’ve made several trips to Oakland Cemetery’s gardens just to spend time photographing flowers from several batches of zinnias that seem especially happy to be here this time of year. The extra attention I gave them got me wondering about the zinnia flower’s structure — especially after looking at flowers like this one, where the zinnia bloom has two little yellow flowers growing around the edges of its central disk…

… about which my first thought was that two additional flowers had seeded themselves (somehow!) onto the zinnia. As is often the case, this puzzling led me to Wikipedia, where zinnias are described as “composite flowers” — and composite flowers are then explained by the botanical term pseudanthium. While “composite flower” and “pseudanthium” are not precisely interchangeable, one can see why one might just be satisfied to use the former term rather than the latter.

Flowers in the aster — or Asteraceae — family are typically composite flowers, and zinnias like the one in the photograph above contain multiple composite parts. In addition to the up-top quotation from A History of Zinnias: Flower for the Ages (I can’t believe I found a book about zinnia history!), you can read a more elaborate description of these intricate structures — along with some diagrams of the different parts of a zinnia flower — at Zinnias: Flower Cycles and Parts. Despite their small size, the additional florets are highly visible in bright yellow or orange, evolving as a strong signal for pollinators (and photographers!) to zoom in for a visit.

I photographed many of these zinnias on a slightly overcast, breeze-free day — my favorite conditions for photographing flowers. Yet as I stood near the zinnias taking pictures, some of them kept swaying to the left or right, as if they were being tapped with a stick. They weren’t of course; but I soon found I had a photo-shoot companion: this bitty creature who, apparently, thought its job was to challenge my focusing skills by leaping from plant to plant and giving the stems a solid shake. I caught him in a nice freeze-frame just after he leapt from his last zinnia, his colors blending with the rock wall as he disappeared into the grass nearby. While I tried to get him to crawl on my hand — THAT didn’t work! — at least I got him to pose for these portraits.

Here’s the first collection of zinnia photos, starting with wide views of some of the red-orange varieties like those I posted previously, followed by closeups of a few other-colored variants with very interesting botanical elements.

Zinnias and Fritillaries

 , , , , , , , , 15

From “Zinnia (Asteraceae)” in Garden Flora: The Natural and Cultural History of the Plants In Your Garden by Noel Kingsbury:

“Named after 18th-century German botanist Johann Gottfried Zinn, the genus includes 17 species, all found from the southern United States into South America, with the most diversity in Mexico. Zinnia species are found in open, often dry habitats. Their rapid growth and short lifespan (annual or short-lived non-clonal subshrubs) illustrate a stress-avoiding nature in harsh environments. Zinnia grandiflora is used in herbal medicine by several Native American communities in Mexico.

“The plants were grown by the Aztecs, and introduced into Europe by the Spanish in the late 18th century. A range of colours was known from early on, probably a legacy of Aztec breeding. Ancestral species vary in colour — Zinnia elegans is purple, Z. peruviana red-orange, Z. angustifolia and Z. grandiflora yellow. One of the strong points of the plants as ornamentals is the ability to get vivid purple, pink, yellow, and orange, all from the same seed packet. They were very popular in the 19th century, suffered something of a decline in the late 20th, and now seem to be on the way up once again.”

From “Agraulis Vanillae” in Butterflies by Quantum Publishing/Oceana Books:

“This butterfly is bright orange with tadpolelike streaks of black throughout. There are three black-encircled white dots on the edge of the forewing. The underside is brown, orange at the base of the forewing, and both wings have elongated, iridescent silver spots. Males patrol for females, who lay eggs on many parts of the host plant….

“The Gulf Fritillary is often seen in flight over the Gulf of Mexico at some distance from any land. They fly throughout the year in south Florida and south Texas, and January to November in the North…. They inhabit pastures, open fields, second-growth subtropical forests and edges, and also city gardens.”

Hello!

A couple of years ago, I posted a few photographs of some of the flowers shown below, three of which included some lovely orange butterflies. At the time, I didn’t know that the flowers were zinnias and simply called them “wildflowers” (see Ten Wildflowers and Three Butterflies), nor did I know (but learned from a comment on that post by Butterflies to Dragsters) the word “fritillary.” These days, I’m much more accustomed to trying to identify the correct names of plants and flowers using PlantNet; and I think I’ve accurately identified the butterflies in these new photos as Gulf Fritillaries — which have an affinity for zinnias and are very common in the southern and southeastern United States. The trio of white spots with black borders on each wing give them away.

The first image below shows one of the clusters of zinnias growing at Oakland Cemetery’s gardens, those zinnias having expanded their territory quite a bit since the last time I photographed them. They thrive in a section of the gardens called Greenhouse Valley that’s located near the center of the property, part of which you can see from one of my autumn photographs from 2019. It’s one of the most delightfully appointed sections of the gardens, where you walk down a hilly, winding pathway from the shadows of trees into the sun, and are suddenly immersed in a fascinating group of architectural structures and plant varieties that give it a distinct appearance.

There was lots of light, very little breeze, and temperatures were in the 70s on the day I took these photos — and the fritillaries were plentiful in these weather conditions. At one point, I counted 20 of them flitting (or should I say “fritting”!?!) among the zinnias, each one showing a distinct preference for the larger red-orange zinnias (Z. peruviana), and spending a lot of time on the flowers enjoying their little drinks. They were all unfazed by my presence — some even briefly landed on the end of my lens — which gave me extra opportunities to concentrate on a few of them and get some decent photos. Their preference for the larger zinnias made things a little easier: I typically focused on and set exposure for one of the flower buds, then just waited until a butterfly landed. It was definitely one of those times when nature photography seemed to synchronize nature and photography into a pleasant, relaxing, and even transcendent experience.

I took this series of photos on September 25, then found the quotation from Garden Flora above, where the author states that zinnias may come in purple, pink, yellow, red, and orange; and the Wikipedia article that lists white, chartreuse, yellow, orange, red, purple, and lilac as zinnia colors. ‘Twas only then that I realized that I had taken photos of just the orange/red zinnias, because there is an ongoing construction project at the gardens to repair drainage culverts and repave roads, and many of the zinnias were inaccessible. I went back yesterday, and found that the rest of the zinnia section had reopened, so I’ll have more new photos of these multi-colored beauties (accompanied by some things I’ve learned about zinnias) in several upcoming posts.

Black-Eyed and Brown-Eyed Susans (2 of 2)

From Kingdom of Plants: A Journey Through Their Evolution by Will Benson:

“Behavioural studies in the twenty-first century have sought to provide a better understanding of the mechanisms by which bees forage. We know now that they do not ‘see’ shapes or objects but instead detect parameters and recognise places, and by using their 300-degree vision they are able to triangulate on just a few clues in order to find food. The patterns that we see in the flowers around us have evolved to play to such perception, and as our understanding of both plant and pollinator increases we are able to gradually unfold more details of the complex relationships that have formed between them….

“The yellow and black of the Rudbeckia petals is a useful clue to help us understand how bees respond to the colour signals from plants, as it tells us that the contrast between colours plays a significant role. There appears to be yet more evidence for the importance of this colour contrast, in the way that non-floral parts of the plant are seen, or not seen, by bees. As the green parts of a plant must be able to absorb light from the sun in order to photosynthesise, much of the UV light that falls on the leaves and stem is absorbed by pigments such as flavanoids and chlorophyll. As a result, for an animal who sees predominantly in the UV region of the spectrum, green vegetation appears almost black. The effect of this is that the UV-reflecting parts of flowers are heightened by the black background, making them more obvious to certain pollinators.”

Hello!

This is the second of two posts featuring a mix of Black-eyed Susans (Rudbeckia hirta) and Brown-eyed Susans (Rudbeckia triloba) from Oakland Cemetery’s gardens. The first post is Black-Eyed and Brown-Eyed Susans (1 of 2).

Black-Eyed and Brown-Eyed Susans (1 of 2)

From “Rudbeckia (Asteraceae)” in Garden Flora: The Natural and Cultural History of the Plants In Your Garden by Noel Kingsbury:

“The name [Rudbeckia] was bestowed by Linnaeus, in honor of his teacher at Uppsala University in Sweden, Olof Rudbeck the Younger, and his father, Olof Rudbeck the Elder. It is the dark centres to these golden-yellow daisies which draw us to them — hence, the common name black-eyed Susans (coneflower is another). There are 23 species, all rapidly growing herbaceous perennials and all native to North America, largely the midwestern and eastern U.S. states….

“Rudbeckias are generalists, growing in a wide range of both open and lightly shaded habitats, from virgin prairie to waste ground, but preferring moister and more fertile soils. Of the species in cultivation, Rudbeckia hirta and R. triloba are short-lived non-clonal perennials, often members of pioneer communities; the remainder are clonal and competitive, often strongly spreading, although not always persistent. Rudbeckias have had a minor role in Native American medicine, sometimes as a substitute for echinacea.”

Hello!

Last week I went hunting at Oakland Cemetery’s gardens for some of the tiny, colorful asters that I’ve previously photographed around this time of year (see, for example Autumn Asters (1 of 3), Autumn Asters (2 of 3), and Autumn Asters (3 of 3)). I was a little too early, as it turns out, finding only tiny buds not yet ready to open — but I did come across some substantial gatherings of the flowers featured in the images below. The first three photos will give you some idea of the flower volume: a bloom-forest teaming with moths, bees, and other wee pollinators bouncing among the “eyes” of these flowers.

Black-eyed Susans (Rudbeckia hirta) and Brown-eyed Susans (Rudbeckia triloba) are members of the Asteraceae family — so I guess I actually did find asters, just not the ones I was looking for. Wikipedia lists other common names for the plants, including Coneflower, Brown Betty, Gloriosa Daisy, Golden Jerusalem, English Bull’s Eye, Poor-Land Daisy, Yellow Daisy, and Yellow Ox-eye Daisy — and many of these names likely have some fun historical roots and local usages. I did asked one of the AI tools if the name “Susan” in “Black-eyed Susan” once referred to any specific person, and here’s what I sort-of learned from ClaudeAI:

There are a few theories about the origin of the “Susan” part of the name Black-eyed Susan, but unfortunately there is no definitive evidence pinpointing exactly who Susan refers to. Here are some of the main theories:

  • One belief is that it was named after an English woman called Susan who frequently handed out flowers, including rudbeckias. This may explain the flower’s association with cheerfulness and hospitality.
  • A common legend says it was named by European settlers for a native Algonquin woman who helped them learn wildflower names. This speaks to its native North American origins.
  • Some think it may be biblical in origin and refer to Susanna from the Book of Daniel in the Old Testament.
  • There are unverified references to individual women named Susan in colonial America for whom the flower was informally named.
  • It may simply refer generically to the archetype of a strong, plainspoken woman, as Susan sometimes represented in folk culture.

Unfortunately there is no solid evidence for any of these possibilities over the others. The name was in use by the late 1700s, but the exact inspiration remains mysterious. So while the “Susan” in Black-eyed Susan is vivid, the specific person or meaning behind it has been lost to history.

It was an overcast day when I took these photos, which made the flowers glow against their dark green backgrounds, and the filtered light accentuated a color shift from yellow toward a more saturated orange. The “eyes” actually vary in color and include both black and dark brown, which helped me differentiate Black-eyed from Brown-eyed Susans.  The brown eyes reflect more yellow or orange shades from the flower than the black ones, on which you may see bits of blue color along with the black.

Iris Domestica, the Leopard Flower or Blackberry Lily (3 of 3)

From Strange Tools: Art and Human Nature by Alva Noe:

“Things show up for us as colorful and noisy. But this is all false appearance, a consequence of our particular makeup and local perspective. The qualities of objects we seem to see wouldn’t get cataloged in the final description of absolute reality. For they are merely effects, in our minds, of processes that are, in themselves, without color and without sound…. Everything we know in the world around us — from mountains to ice creams to sunsets to rose petals to the sun and the earth — is made up of physical parts that are made up in their turn of parts that are made up of still smaller parts. It’s pure matter… all the way down.”

From “The Act of Expression” in Art as Experience by John Dewey:

“[When] excitement about subject matter goes deep, it stirs up a store of attitudes and meanings derived from prior experience. As they are aroused into activity they become conscious thoughts and emotions, emotionalized images. To be set on fire by a thought or scene is to be inspired. What is kindled must either burn itself out, turning to ashes, or must press itself out in material that changes the latter… into a refined product….

[Elements] that issue from prior experience are stirred into action in fresh desires, impulsions and images. These proceed from the subconscious, not cold or in shapes that are identified with particulars of the past, not in chunks and lumps, but fused in the fire of internal commotion…. Through the interaction of the fuel with material already afire the refined and formed product comes into existence….”

Hello!

This is the third of three posts — with images magically remanufactured as black-background variations — of Iris domestica photographs that I uploaded to Iris Domestica, the Leopard Flower or Blackberry Lily (1 of 3) and Iris Domestica, the Leopard Flower or Blackberry Lily (2 of 3). Also, for extra fun, I made a collage of all twenty images and included that at the bottom of this post.

Of all of the photos I’ve converted to black backgrounds, these are the most complicated. As is implied by the quotation from Strange Tools above, Iris domestica is a fine example of something that seems to reveal smaller and smaller parts and pieces, the more you look at it. Here, for example, is one of the photos from my previous posts…

… where you would see the two flowers in the center as the subject of the photo, despite the presence of many other elements. This is correct of course, and I guided your eyes toward seeing the photo that way by Lightroom adjustments that created greater visual distinction between the subject and background, by dimming and softening the background so the pair of orange-and-spotted flowers became more prominent.

Converting a photo like this to one with a black background can be a challenge. Last year I did something similar — see Leopard Flower Variations (On Black) from September, 2022 — where I used Lightroom brushes to paint the backgrounds black, limiting myself mostly to the flower blossoms because brushing around the plants’ thin stems, leaves, and seedpods was too time-consuming. Shortly after that, Adobe introduced enhanced masking tools with the ability to select objects, subjects, and backgrounds, which I’ve been using as much as possible since they became available.

Updates to our post-processing tools serve us best when they open up new possibilities; and with these Lightroom masking enhancements, I’ve tried to take on more complicated variations. Instead of just brushing out the backgrounds around parts of an image as I did in the past, I can now use a combination of masks to get better results. With object selection, I can choose different parts of an image that I want to retain as the black-background version’s overall subject, then invert all those selections, then change the background to black.

Here, for example, is an interim step in this approach. I selected parts of the image as individual objects in a single mask one at a time — the flower petals, the seedpods, and the stems — then inverted the mask (shown in dark green). Lightroom’s object selection got a lot right; but as you can see — look to the right of the flower — some of the stems appear disconnected from the rest. This happens when selected objects are close in color to the background colors, and will also happen where there are similarities in sharpness or contrast between foreground and background.

If I stopped here and converted the background to black, the gaps in the stems would be apparent, as you can see here…

… or, up closer, here:

I often compare the next steps (in my own head, at least) to painting different colors on walls and window trim, where you have to pay attention to the boundaries between two objects (the wall and the window frame) and two colors. If you slip with the paintbrush and one color intrudes onto the other, corrective action (!!) is warranted, along with, perhaps, a bit of cussing and extra bits of patience. But you have to fix it because you know it won’t look right if you don’t.

When adjusting masks that have started out coarse as shown above, I’ve learned that I need to remember that elements of any image tend to be brighter where they’re closer to the camera (or to the eye), and darker toward the back. This light-to-dark, front-to-back brightness variation is one of the ways that we perceive two-dimensional images as having depth, and it applies to even the smallest details. In Lightroom, the masks appear to become “fuzzier” when they partially cover darker, toward-the-back elements. If I adjust the masks too much, I lose the front-to-back appearance of depth and leave the image looking flat — and something as small and thin as a flower’s stem would look like a two-dimensional geometric line, instead of a living portion of a plant. At the same time, I have to deal with an illusion: the more I zoom into a photo, the more tiny pixels appear to need adjustments. It took some practice to keep in mind that front/light-to-back/dark contrast helps us perceive something as “real” and avoid adjusting the masks more than I should.

Since I have to pay close attention while working on the masks, I’ve noticed how familiar I become with the subjects of the photos and all their details. For most of my photos, this means that — even if it’s unintentional — I’m constantly observing the structures of plants and their flowers. This in turn helps me shoot with different expectations about what I see, what I can show, and what level of focus or what kind of light I need, especially if the photos might end out with black backgrounds. This is another valuable characteristic of the software tools we use: they not only offer expanded possibilities, but they help us see something we might overlook, as we envision different ways of taking photographs and enhancing them.

Here you see the corrected mask — where the stems (just to the right of the flower) are no longer disconnected from the rest of the plant. I used a “subtract brush” to erase the black background from areas where it intruded on the plant’s stems.

Now I can turn the mask overlay off, and I’ve got a completed black background. Select the first image below if you’d like to see a larger version, and I’ve included the original starting point for this image for comparison.
