Late summer yellow composite with serrated leaves, found
with Epilobium sp near banks of Coyote Creek, Oka Ponds.

Flowers appear in early autumn, followed by numerous seeds with hooked barbs that attach to
passing animals' fur or clothing or sometimes even skin which allow the seeds to be dispersed
widely. The seeds look similar to a tick and give this plant part of its most popular common name.

This plant is a native of North America, although in some areas it is an invasive
weed. It is known by a variety of different names, including Sticktight, Common
Tickseed, Bur-marigold, Devil's Bootjack, Devil's Pitchfork, Pitchfork Weed and others.
