I bought 3 dierama plants from the UBC botanical garden shop after seeing your display at the Vandusen Garden Show. I was very impressed with the plants that you had as they were flowering. In fact I went out the same day after the show and bought the plants.They were planted according to David Tarrent's instuctions to me . However, none of the plants have flowered. They grew to about 3 feet,and seem to be very healthy.They were situated on a deck in a large pot and had sun until approx. 3 p.m. when they were in shade. Question 1 What did I do wrong ? 2.What do I do with the plants now and over winter?( I do not have a greenhouse). You gave me help previously with a yellow smoke bush, it is thriving and I thankyou for your help.
