Pat - That is interesting about Lavender Stardust. It will be over 2 years now since I received it. Last year it bloomed beautifully for me. It never went completely dormant this Winter either. A few of my other cultivars almost disappeared but not quite, before they started producing new foliage again. Only the two missing plants that I fear died, lost all signs of foliage. I had a warm winter too.
Does dormancy affect blooms?
