Dear Arnold, I got a tuber form BX years ago. Grew and bloomed it, donated tubers and bloomed it again, then gave away the lot. To much trouble. It went dormant in summer heat and is a winter grower. Not very simple in my very cold winter climate. when growing well and in full foliage and flower it is very nice, but it can be grown even here in Kansas City. Best Jim W.

I got one of the tubers of Impatiens flanaganae and have been struggling to grow it. I've tried in the greenhouse under shade cloth, outside in the shade. No luck. > > Do I really need an air conditioned greenhouse to grow this. >
