About
This clump-forming, rhizomatous perennial 20-30cm high, with deciduous, pinnate leaves, 30cm long, formed of usually nine ovate to heart-shaped, spiny-edged leaflets which emerge purple-bronze and mature to green, and dark purple buds which open to flowers of dark pink-purple sepals and pale purple petals with white-tipped spurs in late spring and early summer; Epimedium leaves may be used for their nests by leaf-cutting bees.

Care notes
CultivationGrow in fertile, humus-rich, moist but well-drained and preferably slightly acidic soil in partial shade, with shelter from cold, drying winds; where frosts are prolonged or severe, spread an organic mulch such as leaf mould or composted bark to protect plants over winter
PruningNo pruning required, but cutting back in late winter or early spring, before flower spikes form, will improve appearance
PropagationPropagate by division in autumn or after flowering; or by root cuttings of rhizomes, kept under glass in winter, and planted out after all danger of frost has passed; propagation for resale is prohibited without a licence
Pest resistanceMay be susceptible to vine weevil
Disease resistanceMay be susceptible to mosaic virus diseases and fungal leaf spots
