I have only had Heman for 2 years but I love it!!!! The first summer I had it, it produced one scape and I was blown away by the size of the flowers. I agree that it can be blotchy at times. It is extremely sunfast. For hybridizers, it's pollen is very fertile but I have not been able to set a pod on it. I love how tall it is and it makes for a striking presence in the garden. I haven't had it long enough to see how well it increases but I think it has doubled the number of fans from 2 years ago.
