Blue Star 'Blue Ice', Willow Amsonia 'Blue Ice', Blue Dogbane 'Blue Ice', Willow Blue Star 'Blue Ice', Eastern Bluestar 'Blue Ice'


Compact, Amsonia 'Blue Ice' (Blue Star) is an erect, clump-forming perennial adorned with pretty clusters of periwinkle blue, star-shaped flowers in late spring - early summer. Opening up from plump navy blue buds, they bloom for 4-6 weeks and rise atop erect, leafy stems above a graceful foliage of willow-shaped, bright green leaves. The foliage turns a rich shade of golden-yellow in the fall, extending the season of interest of this plant. Slowly spreading by very short rhizomes, Blue Ice adds a billowy, finely textured element to the landscape. With early-season blue flowers, attractive summer foliage, a sturdy habit and golden fall color, it is a first-rate garden plant.

  • Grows up to 12-16 in. tall (30-40 cm) and 18-24 in. wide (45-60 cm).
  • Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Thrives in loamy, moist soils (but not soggy)! Once established, this plant enjoys some drought tolerance.
  • Undemanding and virtually pest-free and disease-free, Blue Star is a welcomed addition to borders or cottage gardens. Best visual impact in mass plantings.
  • Deer resistant, clay tolerant.
  • If grown in full sun, this plant will not require staking or pruning. In part shade, this plant has a tendency to flop, therefore it will need to be pruned or staked. Cut back by 30% to 50% after flowering to maintain shape, prevent the plant from flopping over and promote a bushy growth.
  • Contact with the milky sap may cause skin irritation.
