E is for Epimedium


One of my favorite groundcovers is a plant commonly called barrenwort, bishop’s hat, or fairy wings and is in the genus Epimedium. There are over 20 cultivated species of Epimediums, most of which are herbaceous perennials, in the barberry family. Most species are native to China or parts of Asia with a few species native to the Mediterranean. Plants have been grown for centuries in Asia. Some hybrids have been cultivated for over 100 years. Many of these hybrids are available at independent garden centers in the US.
