Cirsium horridulum Michx.
Asteraceae (Aster Family)
USDA Symbol: CIHO2
A tall branching stem with large yellow or red-purple flower heads and very spiny, clasping leaves. It grows 1-5 1/2 feet tall, and the leaves are 8-24 inches long. In rare instances the blossom is yellow.
Often found along the edges of salt marshes, it is also a pasture weed in the South, where it is frequently red-purple instead of yellow. Prairie Thistle (C. canescens) also yellow, has leaves white and velvety beneath and grayish above, with leaf bases extending, wing-like, down the stem. It is typical of overgrazed western pastures.
