Asian Blue Star is so closely related to our American native Amsonias that many believe it should be in the same genus. Tough, elegant, cool perennial that rises to 2′ tall and is topped by clusters of NAVY BLUE starts in late spring. Bring on the bumblebees. Forms a slowly increasing clump in rich to average soil with regular summer water. Though established plants can easily handle drought. In autumn the whole plant turns from green to bright yellow and holds that color for an extended time. Very showy. Long lived, hardy perennial for full sun. No pests or disease. Winter deciduous.
