Conoclinium coelestinum

Description

Conoclinium coelestinum, commonly called mistflower, is a late summer to fall-blooming herbaceous perennial that is native to the Eastern United States. It typically grows to 1-2’ tall on downy purplish stems clad with coarsely-toothed, ovate-deltoid leaves.

It looks like annual ageratum and in that regard is sometimes commonly called hardy ageratum.

This perennial can spread aggressively by rhizomes and will do well in naturalized areas and periphery of a stream or pond and in open woodland gardens. Plants will grow in wet areas.
