Plant Biography

Epimedium x rubrum is a hybrid between the species Epimedium grandiflorum and E. pinnatum. It is a deciduous evergreen perennial, spreading from underground rhizomes to make effective ground cover. In spring new growth is beautifully tinted bronze, fading to green until the cool days and nights of autumn repeat the performance. Wiry stems of red flowers sporting creamy white spurs are to be found nestling in amongst the leaves during spring. An elegant and understated plant for shaded woodland borders, perfect to combine with ferns and hostas.

Care & Size Guidance

Care & Size Guidance

This Epimedium prefers good drainage and is able to tolerate moderately dry shade with watering to help establishment. It is slightly faster spreading than other types which makes it a good choice for ground cover, especially as some foliage is usually kept over winter in milder areas.

A mulch of compost in early spring before the flowers in April-May will help produce the most vigorous plants, and large clumps can be divided in autumn to create more stock and increase vigour even further.

Expert Tip

Their tolerance of moderately dry shade makes this a great choice for underplanting beneath large trees and shrubs or at woodland edges.
