‘Blue Ice’ is a cultivated variety (or possibly a hybrid) discovered growing in nursery blocks of native Eastern Blue Star (Amsonia tabernaemontana) which is notable for its compact growth habit and bold, blue flowers. It blooms for nearly a month around May or June and is popular with many pollinators. Just like its parent species, ‘Blue Ice’ tolerates a variety of soils but prefers moist, well-draining sites in full sun.
Its fall color is a rich, golden hue that is a stunning feature in the perennial garden and benefits from mass planting. The tidy, upright growth of this cultivar makes it ideal for the front row of perennial borders and along pathways. Cut it back in late winter/early spring to keep the growth fresh and even. As a member of the Dogbane family (Apocynaceae), its sap produces a milky latex that deters browsing by deer or rabbits.
