Epimedium (Barrenwort)

Epimedium has many common names, Barrenwort is probably the most popular, derived from its ability to grow in places many plants cannot.  Epimedium is also called Bishop’s Hat or Fairy Wings (both referring to the shape of the flowers). When established, this plant will tolerate dry shade beneath trees. Water weekly after planting, gradually tapering down frequency and amount of water. While not a lead role, Epimediums are great supporting actors! In mixed borders or woodlands they complement a wide variety of other shade plants, including Helleborus, Pulmonaria, Aquilegia, Heuchera, Ferns, and Dicentra.
