Planting Instructions: These perennial rhizomous tubers produce magnificient blue umbels perched on top of 24 to 36” stems. Plant top of tuber 2-3” deep in well draining soil in full sun to partial shade. Tubers can be planted anytime of the year, and once established bloom early summer to fall (may take 2 years to establish & bloom). In well draining soil, tubers are hardy to zone 7 if unprotected and may be hardy to zone 6 if well protected by shelter and mulch. In colder zones, use as a patio plant or lift and store for winter. Fertilize moderately. Tubers multiply quickly. Store in peat moss until planting.
