IDS Trees and Shrubs online recounts the murky origins of the species, and we have no idea how many clones are in cultivation in the US, but we do know that this one from Harold Epstein is fantastic, and we thank his gardener, Lois Himes, for introducing us to it. Copper pink new foliage becomes deepest green wth racemes of individually large yellow and fragrant flowers opened as early as December, depending on the weather, but typically February- March. Blue fruit follows in spring. Will take deep, dark shade and always looks unmarred. That said, flower production likely better with more light. Best in part shade. Z6/7, quart pot.
