Facts About

Lance-leaved tickseed is native to the Midwest and Southeast, and is considered introduced in our area. It has an attractive flower and is grown as an ornamental, but it can self-seed aggressively, leading to invasiveness in some situations.

Habitat

Anthropogenic (man-made or disturbed habitats), meadows and fields
