I've had the same problem for the last 10 years or more, with lots of healthy leaves but no flowers. Have tried moving the plants to different parts of the garden all to no result. Some say they are planted too deep, but I've taken soil from around the stems, and that doesn't work either. Some years I get small buds but they turn black and drop off. I don't know what I'm doing wrong, unless they don't like my soil, good on top but clay about a foot down. I've just left them alone with fingers crossed each year that they might just fancy showing me a flower. All mine are the pink ones.
