Epimedium dolichostemon x pinnatum subsp. colchicum.
Description – We were gifted this interesting cross this spring (2015) and looked forward to seeing the resulting flowers, from such a diverse union. It didn’t disappoint. I don’t know whether it would have a commercial future, but as a botanical curiosity I’m sure it will be sought after by Epimedium enthusiasts. It looks as though it will make a medium to large sized evergreen specimen when established. I have no idea who raised the cross.
