Epimedium x omeiensis
This plant arrived at the Arboretum in 1985 and so predates the "epimedium explosion", or at least dates from near the beginning. That's likely why it wasn't assigned a cultivar name. There are a number of x omiensis named cultivars available now. We put it in our "elite plants" program then. If I had to guess, it wouldn't make it today though the flowers are beautiful in an odd sort of way.
