The large section of black-eyed susans has finished blooming and is going to seed.

more than two dozen dark-brown seedheads, with only a few shriveled petals remaining

But just when I thought it was the end for these flowers, a somewhat hidden section popped up a few feet away.

They are a welcome sight as the garden is starting to fade.

Black-eyed susans that are opening look like they’re sleepy and having a hard time waking up.

My hair is a bit wild in the morning, too.

another flower farther along, the petals on the left sticking straight up, and the petals on the right starting to fall into place

One last stretch, and then this one will be ready.

At the end of the day, this one looks like it’s ready for sleep.

All tucked in for the night. This doesn’t look comfy to me, but what do I know? I’m not a bee.

If I were giving out an award for the most social flower of the year, black-eyed susan would win. One fun day, I spent the morning checking and rechecking on them, noticing and admiring the diversity of insects that were attracted to the blossoms. About two-thirds of these photos are from that one day alone.

Bees:

likely a bumblebee on the right side of the center disk, facing downward

metallic green been in the same position

unidentified smaller bee on the left of the center disk, curled and facing downward

possibly a megachile, on top of the center disk, with legs full of orange pollen

Flies:

really big fly with hairs, possibly a tachinid, on top of the center disk

long-legged fly standing out on one of the petals

Flies that look like bees:

bee mimic with a wide abdomen

much smaller bee mimic, or hoverfly, hovering to the left of the center disk

Butterflies:

tattered monarch sitting on the right side of the flower

Eastern tiger swallowtail with wings outstretched, tilted toward the camera, on the right side of the flower

Bees and butterflies:

gray butterfly, possibly a hairstreak, on the left side, and a long-horned bee on the right, their antennae crossing in the middle

Lacewing:

sitting on a petal in the front of the picture, facing downward

Aphids:

a blurred stem with two large red aphids and several smaller red aphids, in front of a black-eyed susan

Beetle:

beetle perpendicular to a tall center disk, with a dark red body and wing shells that blend in with the flower disk

Japanese beetle doing the splits:

beetle on the petals facing up

Leafhopper:

small green insect tucked into the fold where the petal meets the flower's center

I don’t know what this is:

patterned brown insect with long antennae, climbing up a tall center disk

Inchworm:

skinny green caterpillar holding onto a petal with its head hidden behind the center disk

And my favorite find, a camouflaged looper inchworm:

curved brown caterpillar hanging off the right side of the center disk

(More about this camouflaged looper caterpillar.)

There was also this gruesome find — one dead bee on a petal, with two dead bees and one dead fly suspended below — but then again, a spider’s gotta eat, too. (I assume that’s what created this scene.)

With so many dozens of black-eyed susans in our garden, we were bound to spot some flowers that didn’t grow quite perfectly. Here are some examples.

One petal that remained fused:

black-eyed susan in bright sunlight, the petal at the 3 o'clock position looks a bit like a cornucopia

Irregular center disks:

the brown center has eight growths, some pointed and some flat, around the circle, and a thin, curvy yellow growth out the middle

cone-shaped center disk, with a smaller one pointing to the left growing out of the left side

two cone-shaped centers on one flower, mostly connected but separated near the top

Another type of irregular center, a condition called fasciation that causes elongated growth that’s usually in the stem, which causes the flower to be elongated too:

a really large roundish center that's about double the normal width, with petals hanging below and a couple petals strangely growing out the top right

(I left this flower in the garden, since fasciation is not contagious.)

Aster yellows, an incurable condition caused by a bacteria that’s spread by leafhoppers:

black-eyed susan with narrow petals that are light green instead of yellow

six brown centers without any petals

(These affected sections of flowers were removed, because aster yellows is contagious.)

Curled petals that seem to be caused by the tear / hole near the tips:

yellow flower with some narrow red in the center of the petals, all but three of the petals curled under, viewed from above

It’s a pretty effect, but it happened to many flowers, so I’m curious whether it’s something to be concerned about. I haven’t been able to find any information about this yet.

Long petals, short petals. Skinny petals, wide petals. Single color, bicolor. You name it, we saw it somewhere in the garden this year.

rudbeckia with long narrow petals
rudbeckia with medium length and width petals
black-eyed susan, viewed from above
rudbeckia with short wide petals
rudbeckia with a very light red center and wide petals
rudbeckia with a small light red center and few petals
rudbeckia with a small dark red center and wide petals
rudbeckia with a large very dark red center

The red ones likely came from a seed mix a few years ago. They started in a flower box and are now spreading on their own and may be intermingling with the native, solid-yellow, rudbeckia hirta. I think they’re called “gloriosa daisy” though which specific variety, I’m not sure; perhaps there are more than one, which is why there’s such variation.
