Technically, a pricker bush is the generic name of a family of plants. The family is called Asteraceae. Not all plants are spiny. It consists of the Bull Thistle, Canada Thistle, Perennial Sowthistle, Yellow Hawkweed, Orange Hawkweed, Dandelion and several other Dandelion look-alikes. None of the plants are poisonous. Although the term Pricker Bush applies to the family, most use this term to describe the Bull Thistle, a plant the resembles a Dandelion with large, sharp spines on its leaves. It may grow as a patch or as a wide, tall bush of spines.

Velvet leaf, common yarrow, purple giant hyssop, white snakeroot, dog bane, white sage, orange hawkweed, loosestrife, mayflower, cinquefoil, and violets grow in Minnesota. Many of the state parks have special events to help the people learn more about wildflowers.
