The bloom period is relatively long - lasting from early spring, well into fall. Wildflower garden.

The range of this species covers much of North America, especially the midwest and mid-to-north Atlantic states and extends into southern Canada.  Florida is the southern limit, and locations documented by herbarium specimens are scattered.  Warm winter termperatures likely interfere with reproduction, and at least one of the southern herbarium specimens appears to be at a location where it could have been deposited by a bird.  Once established, this plant should be an attractive bloomer. Specimen tree.
