Description
Epimedium × rubrum is a deciduous perennial, spreading by rhizomes. It is about 30 cm (1.0 ft) tall. When the young leaves emerge in spring, they are tinged with red. The leaves also turn red in the autumn. The flowers appear with the young leaves in spring, and are borne on a loose raceme. Individual flowers are about 2 cm (0.8 in) across, with red sepals and yellow petals.[2][3]
Cultivation
Epimedium × rubrum is recommended for cultivation in shade or part-shade in moist soil, although it tolerates drier conditions when well-established. Old foliage should be cut back before the new leaves and flowers appear in spring.[2][3] It was given the Award of Garden Merit by the Royal Horticultural Society in 1993, with a hardiness rating of H7, meaning that it is very hardy, withstanding temperatures below −20 °C (−4 °F).[2]
