About
Rubinkrone' is a clump-forming, rhizomatous perennial 25cm high, with deciduous, pinnate leaves, 30cm long, formed of usually nine ovate to heart-shaped, spiny-edged leaflets which open flushed with bronze and mature to light green, and flowers of plum purple sepals and rich pink petals, with white-tipped spurs, in spring; 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
Pest resistanceMay be susceptible to vine weevil
Disease resistanceMay be susceptible to mosaic virus diseases and fungal leaf spots
