As beautiful as the Greek name sounds, Dicentra eximia is relatively undiscovered by the Sedum-blinded Green Roof plants experts and by the yearning LEED point collectors. The beautiful flower is native Genus to Northeast United States and Asia that comes in many “faces” (Species and several cultivars).
Leaves are finely divided and gray-green, growing from the base of the plant.
Flowers are pink and bloom in tight clusters at the top of leafless, fleshy stems above the leaves from mid-spring to autumn. The four petals are connected at the base. The two outer petals are pouched at the base and bent back at the tips. The inner petals are perpendicular to the outer petals and connected at the tip. The pistil is enclosed within the inner petals, and the two stamens are on either side. There are two tiny, triangular, pink sepals above the petals.
If the ants would have been a litter quicker in the last 150,000 years these plants would have spread over the entire North America already. However, with green roofs there is a chance to help nature along in this process.
