Epimedium x setosum
26th April 2008
A naturally occurring hybrid between E.diphyllum and E.sempervirens. I have only ever seen this white flowered form in cultivation.
(Epimedium 'Sasaki' ,(E. x sasakii) has the same general parentage and could probably be absorbed into the name. Epimedium x setosum SASAKI GROUP
might be its ultimate fate.)
