|Dicentra eximia / eastern bleeding heart
As the flowers are pollinated and fade, small pea-like pods take shape and 4-6 weeks later beautiful shiny black seeds are ready for harvesting. You can see the seed color through the pods so you know when to harvest. Soon after the pods pop open and a natural reseeding cycle starts in the garden. Not to worry, this is not an aggressive plant. One of the joys of growing species plants is the gentle migration of native plants through the garden.
Finding this plant in anything but a native species nursery is difficult. You will find many bleeding heart hybrids, some using D. eximia as a parent. Just know that no hybrid will come true from seed. Seek out a local native plant nursery and ask if they grow this wonderful plant.
