Amsonia 'Blue Ice'

Amsonia tabernaemontana
A natural hybrid foundling, 'Blue Ice' has richer blue starry flowers that bloom from decorative navy blue buds, and a longer bloom time than most. Bushy and vigorous, it is tolerant of many soil conditions and is low maintenance, with no pest or disease problems, plus no dividing is needed for 6 years! The leaves turn flaming yellow in fall, combining beautifully with lavender blue asters.

WHEN TO SET OUTSIDE
This late-spring to early-summer blooming perennial should be placed in the ground in springtime after all danger of frost has passed.
PLACEMENT & CULTIVATION
Since Amsonia is not appealing to deer, don't hesitate to place this native plant in more natural, edge-type settings to attract bees and butterflies. It will grow best in a soil that is rich and well-drained in full sun, or part sun in drier locations. Place en-masse for best show. Dividing is rarely necessary.
Final Spacing:
1.5-2'
Water Requirements:
Medium Water Use
Watering Details:
Keep moist, especially in full sun, but do not overwater—somewhat drought tolerant in partly shaded sites.
Soil pH:
This plant prefers neutral pH levels but will grow in slightly acidic to slightly alkaline soils.
Fertilizer:
Mix in a couple of inches of compost when transplanting and topdress with a thin layer annually thereafter. Alternatively, feed in spring with an organic granular fertilizer—a handful worked into the soil around each plant should do.
Diseases & Pests:
Amsonia is occasionally susceptible to rust, but this can be prevented by applying an organic fungicide every week or two, June through September.
