The flower head of a composite, similar to a Black-eyed Susan (Rudbeckia), but with a yellow head. The rays (petals) had dropped:
From a planted wildflower meadow – earlier in the season, this meadow was packed with a dozen different types of Rudbeckia. Now that fall has come, there are white asters blooming, crowded with feeding bees, Painted Ladies, Cabbage Whites, and Clouded Sulphurs. The Rudbeckia are mostly long past, with a few remnants, including this flower.
The meadows in my area are starting to go brown. There are numbers of asters flowering – white and blue asters (Symphyotrichum species), and New England Aster (same genus). These are seeds and floss of a tall aster or other composite that bloomed earlier in the season. As walk through the meadow, they look like bright cotton balls. As you get closer, you see the mass of fine floss and the seeds:
A fall leaf provided the background color.
I’m guessing that this is Persicaria maculosa, lady’s-thumb smartweed, but there are many similar species:
The flowers are attractive seen close up, but otherwise this plant really is weedy. I pull it up armfuls of it in my garden, year after year. It’s a native plant (if my ID is correct), I’ve read that Native Americans used it to cure poison ivy. Taken at high magnification and stacked.
This image began as a closeup of a bachelor’s button, with selective focus on a few parts of the flower. Then a tiny aphid-like insect crawled onto an anther:
As I watched, it crawled up to the top of the anther, perhaps to feed on the pollen. My shutter speed was too slow to catch those poses. Then I noticed two more, perching on other flower parts:
It’s the same flower, with focus moved a few millimeters behind the focal point in first image. That may give you an idea of how little depth of field there is at this magnification (around 2x or so) – the flower parts in the first image are hardly visible.
Now I’ll have to try to identify these tiny insects…
An extreme closeup of the frilly edges at the center of a nasturtium:
Most years I grow nasturtium in my vegetable garden. A few of the flowers make it in to salads, but I don’t think I’ve used one in a photograph before. There’s lot to see in the flower center of a nasturtium, this is just one view of many. The yellow patches are anthers.
A field of wild sunflowers (Helianthus spp):
At least, I think they are a wild sunflower species. I had just a moment or two to capture them when the sun went behind a passing cloud. The light was still bright, but this look more is pleasing to my eye than full sun.
When the flower fades it turns into an annoying burr that can attach to almost anything. The image is a closeup abstraction, stacked for a little extra detail on the anther points. Looks a bit like an anemone in this view. Not a native plant, I’ve read that it’s valued as edible for flavor and nutrition – for me it’s the burr that I remember and avoid.
A closeup of a single Deptford pink:
A high-magnification image, stacked for more detail at the flower center. The intertwined pistils were what caught my eye. I tried some views that were even closer, but it was hard to capture the spiky details at higher magnifications.
