- Rocky ground along bluffs, glades, and ledges. Also found in wet woods and in cultivation.
- Native to U.S.
- This species is becoming popular in cultivation because of its showy flower clusters and the fact it is native. Typically the plant is shrubby but it can be grown as a small tree. The plant was used medicinally by Indians and more modern physicians to treat many ailments from congestion to infections. It is not used much anymore.
In Missouri the plant is found growing wild only in a few southern counties. It is cold tolerant and can grows as far north as New Jersey.
