Epimedium (ep-im-meed-um) Barrenwort, Bishop’s Hat, Barberry Family (Berberidaceae). Choice, low growing perennials, with almost evergreen foliage, and loose sprays of florets. With its charming irregular, bicolor flowers, in spring, plant Epimedium in large groups for effectiveness in a border, wild garden or as a ground cover under trees. Also, a lovely and graceful addition to the rock garden. Cut flowers will last several weeks in water.
Epimedium is best planted in partial shade, with consistent moisture, and rich loamy, well-drained soil. Once established, Epimedium will spread slowly but steadily. Tolerant of full shade, foliage will usually burn in full afternoon sun. Also tolerates drought and dry shade (rhizomes hold moisture) once established. Epimedium is intolerant of alkaline soils.
