Bull Thistle

Cirsium vulgare


This introduced wildflower is considered a noxious weed in many parts of North America. The leaves, flower buds and parts of the stem are very prickly. The flowers are purple and without rays. It grows well in disturbed areas and spreads easily by seed. The flowers and seeds are food sources for many insects, birds and other wildlife. The stems and taproots of young plants are edible (stems need to be boiled and peeled).


Border area between open, grassy campground and temperate forest. Nolin Lake State Park, Kentucky.
