A UK National Collection

I was given this plant by the late David Barker who held a National Collection of Epimediums at Danbury in Essex. He said he thought it was an E. stellulatum. I now think it may be E. pubescens. A couple of years ago it was the earliest Epimedium to be in full flower outside in the garden.
