Tall thistle is a striking native biennial that produces large purple flower heads on sturdy stems from summer through early fall. This plant can reach up to 6 feet tall and provides excellent late-season color in prairie and naturalized settings.

Works well in: backyard only.

Wildlife value
Host plant for painted lady butterfly.
The purple blooms are magnets for bees, butterflies, and beetles during late summer when many other flowers have faded. Seeds provide food for goldfinches and other birds in fall.
