Blue Star 'Storm Cloud', Willow Amsonia 'Storm Cloud', Blue Dogbane 'Storm Cloud', Willow Blue Star 'Storm Cloud', Eastern Bluestar 'Storm Cloud'


Noted for its heat and humidity tolerance, Amsonia 'Storm Cloud' (Blue Star) is an erect, clump-forming perennial adorned with pretty clusters of pale periwinkle blue, star-shaped flowers in late spring - early summer. Blooming profusely for 4-6 weeks, they rise atop erect, near-black, leafy stems and cover the foliage of willow-shaped, silver-veined, olive green leaves. Storm Cloud often reblooms for many weeks afterward. The foliage turns a rich shade of golden-yellow in the fall, extending the season of interest of this plant. 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 24-30 in. tall (60-75 cm) and 38-42 in. wide (95-105 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 is somewhat drought tolerant.
  • 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.
