Hardy zone yellow leaved barberry
I am looking for a yellow leaved barberry. There are many varieties out there. Goldnugget, sunsation, Aurea come to mind. Has anybody had any success growing them or any other variety in zone 3? I know that the Aurea barberry color gets scorched in full sun. I know they are not as hardy as the purple rose glow barberry, as most are rated as zone 4.
