I was given D. anglica & D. filiformis this Spring and I put them outside for the Summer & Fall. By November, they were looking pretty ragged. So I brought them to the lab, in a 65-70 degree room. It has been now been two months and the D. binata is sending up two new leaves. D. filiformis had turned totally black and I had given it up for dead. Now I see green growth emerging. Both plants are supposed to be non-dormancy cultivars, having successfully "died back". Is it too soon for them to be coming to life? Is the realtively warm temperature and / or the slightly lengthening photoperiod kicking in?
