E. × youngianum

 

Epimedium x youngianum

Fertile, deciduous clump-forming hybrids between E. grandiflorum and E. diphyllum, mostly of garden origin although they also occur in the wild. Flowers extremely variable in size, shape, color and spur length. Since 2nd  generation offspring resemble either parent, we wonder whether some of the plants we grow as E. grandiflorum are hybrids. Leaflets variable in shape and size. Most produce a second flush of growth and some re-­bloom. Later to bloom than E. grandiflorum.

***2000 Cobblewood Introduction***


A Darrell Probst hybrid from a cross between E. grandiflorum var. violaceum and E. x youngianum ‘Pink Star’. Unlike other varieties where the purple spring foliage emerges at its darkest, and then fades, these small, semi-evergreen leaflets unfurl a greenish-purple and deepen to black-pur­ple.
