Could this be E. sutchuenense?
Epimedium sutchuenense Cc 990394
Distribution - China, Sichuan province.
Description – A small growing evergreen species, which we have yet to flower. It appears to have some similarities with E. leptorrhizum, in as far as the rhizomes are long and searching and the leaves are not too dissimilar on casual inspection. We may have unknowingly flowered this species under a numbered ‘species’ plant. When the named plant eventually flowers we will have a better idea.
