-
Red Barrenwort is a ground cover from Europe. It tends to spread faster than most epimediums but is not weedy. The foliage is showy with heart-shaped leaves that have a red tinge in spring and fall. The flowers appear in clusters in spring with creamy white petals surrounded by red sepals. The flowers resemble columbine.
The plant grows to 1 foot tall and can spread to 2.5 feet wide.
It prefers light to full shade, average to organically enriched soil that is moist to dry and well-drained. Drought tolerant once established. Prune old foliage in late winter or early spring before the flush of new foliage. Large areas of this plant can be mowed as a form of maintenance.
Use this plant in shade borders, walkways, woodland settings, under trees, or in rock gardens. It can also be planted in xeriscapes conditions, where the need for watering is reduced or eliminated.
This is an artificial hybrid that is a cross between E. alpinum and E. grandiflorum.
Insects, Diseases, and Other Plant Problems: No significant problems. Mosaic virus can be transmitted by aphids. Occasionally visited by vine weevils.
