Plant Pick: Bishop’s Hat

Latin name:  Epimedium versicolor

by Vancouver Island Master Gardeners Association

Epimediums are a gift from Asia to Pacific NW gardeners.  This underused plant is easy to grow and has visual interest year around.  The attractive evergreen foliage is highly coloured and if trimmed to the ground in late winter reveals a show of spring flowers in a variety of yellows, golds and pinks.   

The Barberry Family includes two native favorites including Oregon grape and vanilla leaf so it is not surprising that another genus in this family is well adapted to our climate.  Epimedium versicolor is a hybrid between E. grandiflorum and E. pinnatum and has given rise to a variety of mostly sterile clones propagated by rhizomes.  This perennial with colourful semi-evergreen foliage is a wonderful ground cover in semi-shaded areas under trees.  Splendid in massed plantings it holds its own against weeds and pests and drought.   E. x versicolor ‘Sulphureum’ is one of the best cultivars and its two-tone butter yellow flowers are carried in delicate sprays on wiry stems in early spring.
