Plant notes

Bright, orange flower clusters about 2 inches wide bloom at the top of the plant in early July. This species was one of the least attractive to natural enemies in the mid-season.

Habitat

Butterfly weed grows in full sun to partial shade and very dry to average soil moisture. It is found in fields and along sandy roadsides and is naturally occurring in woodland openings and dry barrens. It is generally associated with dry prairie, pine and oak barrens.

Cultivation and management

This plant can be grown from seed to flowers in the third year, or plug material, flowering in the second year. However, it did not establish well from plugs in our full-sun, average moisture site.
