EPIMEDIUM

Variously known as barrenwort or bishop's that, this genus of 25 species of rhizomerooted herbaceous perennials is found from southern Europe to Japan. The leaves, which are roughly heart-shaped with shallowly lobed or toothed edges, are sometimes evergreen in mild climates but are usually deciduous and may color well in autumn. Sprays of small, dainty, 4-petalled flowers appear in spring as the new leaves expand. The flowers may be white, yellow, pink, or red, depending on the species, and may continue into early summer. Epimedium extracts, sometimes known as "Yang tonics," are used extensively in traditional Chinese medicines are are also found in commercially available herbal pick-em-ups.


CULTIVATION


Very hardy and suitable a ground covers for woodland situations, in rockeries, or perennial borders, these tough little plants are easily grown in partial shade in fertile, moist, humusrich, well-drained soil. Propagate by division in late winter just as the new growth appears, or raise from seed.


Top Tip


Though relatively slow-growing, Epimedium species do well in shady spots, and are ideal for planting under trees. They are equally happy in containers, and are a versatile addition to the small garden.
