We forecast this North American native to be a garden phenomenon! This Storm Cloud rolls in with near-black stems and olive-green, silver-veined foliage. Billowing, periwinkle-blue, star-shaped flowers cover the foliage in late spring. Breathtaking! Amsonia Storm Cloud thrives in northern and southern gardens. Younger plants are vase-like and then mature to a wide mounded habit.

A great alternative to shrubs. Drenched in tall flower clusters atop strong stems, Bluestar is stunning in cut-flower arrangements. Low maintenance, heat and humidity tolerant and deer resistant, Amsonia Storm Cloud threatens to become a favorite!

Amsonia General Information

Amsonia are low maintenance mid-western and southern natives that are easy to grow and unbothered by pests or insects. Plants are fairly drought tolerant once established. Exceptional fall foliage color extends the appeal. Adapts to most conditions. Becomes leggy in too much shade. Optimum effect when massed. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Amsonia Plant Care

Easy to grow, best in a moist, fertile soil. Can tolerate wet soils for short periods. Shear back by one third after flowering to maintain a more compact plant. Snap off mature seed pods to prevent over seeding. Bluestars will readily cross pollinate with other Amsonia nearby. Clumps can be divided in spring but this is generally not needed for 6 years or more.
