Bonanza has been in my garden for over 20 years, one of the first I bought. It has been divided, moved and shared a few times. It grows to be a good sized clump at a moderate speed. It is not fussy about anything here. It grows taller here than registered -to 30". The blooms always look the same one to the other and do not fade in direct sun. The bud count is 10 on 3 way branching. Although it is registered to rebloom, that does not happen here. It is a good garden plant.
