I like this spiny evergreen Epimedium a lot. It was bought by David Sisley of Straight Mile Nursery as E. latisepalumfrom, a wholesale nursery a few years ago. He bought three plants and there were two different varieties at least amongst them. My guess these are Chen Yi plants, but this one may or may not be a species. It has similarities with E. ilicifolium and E. wushanense, but more with the former. David  also likes the plant and is building up stocks for sale. He has decided that as it doesn't fit E. latisepalum, or doesn't appear to be definately anyother species, to name it E. 'Dark Secret'.
