A favorite nectar source of Mourning Cloaks and other early butterflies. This is a large carefree plant and shade tolerant. Light blue flowers bloom in Spring. Likes moist soil but reasonably drought tolerant once established. They have a long season of interest which is useful in perennial borders, wild garden and wildlife gardens. They have a shrubby habit so it tends to be useful in mass plantings.
