About

Amsonia elliptica is a perennial plant that grows in an upright clump. Its lance-shaped leaves are glossy and bright green, measuring between 3 to 7 cm in length, and they transition to shades of golden-yellow and pink in the fall. In late spring and early summer, this species produces open panicles of pale blue, star-shaped flowers on upright stems, with a second bloom occurring in September.
