It bears usually solitary, single creamy white to pale pink blossoms that are cup-shaped and elegant. The blooms measure 3 to 4 inches across and have pale yellow stamens.

A garden favorite for many years, bleeding heart has soft green foliage and 1-inch-long rose pink and white heart-shaped flowers for several weeks in spring. Plants can form clumps 3 feet across and almost as tall. Foliage generally goes dormant in summer, so be sure to choose companion plants carefully so there isn't an empty space left in the garden.
