Blue Ice Bluestar

‘Blue Ice’ is a compact, clump-forming bluestar selected for darker lavender-blue flowers and a shorter, sturdier habit than many Amsonia. Its star-shaped flowers open in late spring, while narrow dark green leaves remain attractive after flowering. The cultivar adds a neat flowering mound to borders, rock gardens, and open woodland edges. ## Size and placement Expect a plant roughly 12–18 inches tall; published spread descriptions vary from about 1–1.5 feet to around 2 feet, so leave space for a gradually widening clump. Full sun to part shade is suitable. Moist, well-drained soil supports steady growth; afternoon shade can extend flower display in hot climates, while too much shade may loosen the stems. The Chicago Botanic Garden lists USDA zones 4–9 and notes that the plant is less prone to flopping than many bluestars. ## Identity and seasonal interest The Chicago Botanic Garden and University of Kentucky list the cultivar as *Amsonia tabernaemontana* ‘Blue Ice’. Their profiles describe its compact habit, darker blue flowers, and late-spring bloom. Amsonias generally develop yellow-to-gold autumn foliage, though the cultivar-specific display varies. [Chicago Botanic Garden](https://www.chicagobotanic.org/plant-information/plant-finder/amsonia-tabernaemontana-blue-ice-blue-ice-blue-star) reports May–June flowers and USDA zones 4–9; [University of Kentucky](https://nursery-crop-extension.mgcafe.uky.edu/content/amsonia-tabernaemontana) describes a 12–18-inch compact selection. ## Maintenance Water during establishment and prolonged dry spells. In an appropriate sunny site, this compact selection generally needs no routine cutting back or staking; remove damaged stems as needed.
