Graceful arching branches of heart-shaped droplets, early season color and coveted cuts. Need another reason to love bleeding hearts? They share. Their garden space, that is. After their delightful spring show, bleeding hearts slip into dormancy, leaving the space for other plants. Partner bleeding hearts with shade perennials that shine later in the season, like broad leafed hostas and feathery astilbes, for optimum use of your garden space.
