The two blue-star species from continents other than North America (this and A. elliptica) are also anomalous in other ways, particularly in their relatively compact habit compared to most New World Amsonia. The species that gave rise to the cultivar 'Blue Ice', Amsonia orientalis is almost a shy grower, well suited for smaller garden niches where something special is needed. Full clusters of good blue flowers in late spring are held on upright tightly clumping stems densely clad in healthy lance-shaped leaves that go yellow in fall.
Full sun to light shade; most soils; 15"x15"; late spring; Zone 5
