Can only repeat.........beautiful long flowering and healthy for me. I wonder if micro climate has something to do with it. Bought it 12 months ago now and it has not had to suffer from any real cold weather.
Kent61a, it will be interesting to read what RHS has to say to you ....they sell this plant!
Collecting another plant today and the recipient area will be of similar quality...viz., dappled shade, good deep soil, reasonable moisture. But, again, we don't have severe winters!!
