Discussion | The natural range of Dicentra eximia extends along the Appalachians from North Carolina and Tennessee to Maryland and Pennsylvania. It is frequently cultivated and sometimes escapes outside that area, but it evidently has not become truly naturalized beyond it. Such garden escapes, perhaps including misidentified plants of D. formosa, also widely cultivated, are almost surely the basis for reports of D. eximia from Illinois, Michigan, Ohio, New York, Connecticut, and Vermont. Several patented hybrids between Dicentra eximia and D. formosa are sold in nurseries. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
