Kaktus said: Never seen any Pumila that has purple stress color, only seen some red one, I bought a red one last year, but turned back into green.
Agree with Steve in chopping the stretched Pumila, but it I will wait until it is bigger in size.
Did you buy those from China? 3 weeks, I will be more stressed than the plant if I know the plant was in shipment for 3 weeks.
