I have Miss Kim in full bloom now. I love the fragrance most of the time; other times it seems a little overwhelming.
I can't grow Delphinium either. I think it is as much the humidity as it is heat that makes them out of reach. I grow about 90% from seeds and another struggle for me is Persicaria orientalis. I've tried all the prescribed methods and I am lucky to get 1 or 2 to germinate. This year that number is zero.
Hollyhock rust is a problem too. If I grow the shorter annual types I have better success, but I would love to have the towering giants I remember from childhood.
