I only have a small handful of named cultivars that are over two years old, 90 per cent of mine have been acquired in the last two years, the majority this year. I just noticed 'David Kirchhoff' is developing its first non terminal branch and it was planted last year. I have come to the conclusion in my garden it takes at least three years (not there yet) to get a "good feel" for the plant, seems it takes that long for most of them to mature. So I am not able to post many meaningful comments yet.
