I haven't had Tranquil Waters too long, I think 3 years and it does well in my climate. It is not a fast increaser. Scapes are very tall here. This year I think scapes are over 40". I usually have fairly good bud count but this year bud count appears to be low as is on a lot of my other flowers. The plant is fertile both ways. I have not yet grown out any seedlings from it but I really should try. It has a lovely flower that opens up nicely and does well in hot weather.
