Amsonia tabernaemontana

Useful in a border, at a woodland edge, or in a wildflower garden, the genus Amsonia is made up of about 20 species of clump-forming perennials that bear long-lasting, narrowly funnel-shaped blue flowers that resemble small stars. They bloom from spring to summer. The leaves of some species turn vibrant yellow in the fall, adding another season of interest. The foliage is attractive throughout the growing season, regardless of fall color. Amsonia are native to woodland and grassland in southeastern Europe, Turkey, Japan, and the northeastern and central U.S.
