Amsonia Blue Ice (Blue Star)
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.
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 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.
