Tall, coarse-leaved, upright plants produce loads of fluffy, deep purple blooms in clusters 3-4" wide in late summer/early fall. Nice for the back of the garden or in meadow plantings. Butterflies are quite fond of this long-bloomer. Native.
Prefers full sun. Usually found in moist thickets, ditches or stream side, it prefers evenly moist to wet soil, but tolerates short periods of dry conditions. Great for rain gardens.
Plants may be cut back early in the season to reduce overall height. Remove seed heads before they disperse to prevent self-sowing. Plants will adapt to almost any moist soil and are great for wet areas at the edges of ponds.
