About Bluestars
Amsonia (Bluestar) is a genus of roughly 18-20 herbaceous perennial species in the dogbane family, Apocynaceae, the great majority native to North America with two Old World outliers -- A. orientalis from the eastern Mediterranean and A. elliptica from East Asia. Only a handful of species and their cultivars are widely grown in gardens. Across the genus, plants form tidy clumps of wiry, upright-to-arching stems clothed in narrow to willow-like leaves, topped in spring by loose clusters of small, star-shaped, five-lobed flowers in shades of pale to steel blue. What distinguishes the genus in the landscape is its exceptional autumn performance: most bluestars turn brilliant gold to butter-yellow in fall, a trait that -- along with drought tolerance and deer resistance from its milky, bitter sap -- has made the genus a favorite of garden designers.
