Eastern Blue Star Overview

Amsonia orientalis is a clump-forming, woody, perennial species from the Apocynaceae family. It is commonly known by the names Eastern Blue Star and Blue Star. It has narrow, lance-shaped leaves and its light to dark blue star-shaped flowers are borne on erect stems in summer. Originally from Greece and Turkey, Amsonia orientalis likes full sun or partial shade and prefers a moist, well-drained soil. It can however, tolerate long periods of dry weather. Therefore, it can be planted in prairie-style planting schemes, in dry flower beds and is often seen at the front of informal/cottage-style garden borders.
