Dark green leaves form an upright plant through most of the summer months, creating a great background for other spring and summer flowers. Come late summer, large buds form on the stem tips and deep blue-violet flowers bloom throughout September. Great massed to create cover for a variety of wildlife.

Foliage and roots are bitter-tasting, herbivores leave it alone
Slow growing but long lived perennial
Once established, needs little care
Moist woods and swampy areas from North Dakota south to Nebraska and east to New Hampshire and Virginia.

Prefers moist, humusy, acidic, well-drained soils in part shade. Does not grow well in the deep South because of high night time temperatures.
