From the moment this hardy prairie perennial emerges in spring, its smoky purple leaves make a statement. This long-blooming plant produces its first flowers in early July and continues to bloom until early fall. As the buds open, the petals are a stunning vibrant reddish-orange that gradually fades to golden yellow. At the height of summer, ‘Bleeding Hearts’ puts on a spectacular multicolored show, with individual flowers persisting for more than four weeks. New flowers form on top of old flowers, hiding them and making deadheading unnecessary or most of the time. Deer generally find this plant repulsive—unlike pollinators, who love the flowers. It tolerates clay and rocky soil as long as there is good drainage. Water regularly during long dry periods for best flowering.
