Butterfly Garden

Yellow coneflower

This yellow coneflower, native west of the Mississippi River from Missouri down to Texas, is easy to grow in most well drained garden sites. It typically reblooms with out deadheading, although will self-seed when spent flowers are left in place. The erect seed heads are attractive and prove inviting to goldfinches and other birds throughout the winter.

Balloon plant

This native southeast African plant is a wonderful butterfly plant. Its clusters of white flowers are insigificant but the light green balloon-like seed pods make it a great plant for a border and as a cut flower. It can be an agressive self seeder so care should be taken. It is most commonly sold as Asclepias physocarpus.
