Tick seed

A quick look at the Internet shows that there are actually dozens of flowers that are called Tickseed, though I think this one is most commonly identified as such. (Some of the plants that hold this name are members of the same family, while sometimes the title seems loosely applied to any kind of yellow daisy.

Like the Willow-leaf Sunflower, this member of the sunflower family grows in big hedgey bunches, and is a dominate part of Arkansas's Indian-summer landscape. It might be indistinguishable from the Willow-leaf sunflower except for these attributes: the Tickseed sunflower has 8 petals, opposed to the Willow-leaf's fourteen. Beyond that, the bloom has a notable cup shape, and the leaves are slightly thicker with a jagged edge.

I've noticed that around our place, tick seeds seems to be one on the longer blooming wildflowers. We have a succession of different sunflower species in bloom throughout the summer. (Virtually none of them can I ID beyond sunflower.) However, tick seed begins blooming in June and continues through the fall. That -- and it's proclivity for growing in clumps -- makes it one of my favorite wildflower even if it doesn't have a very showy bloom.
