This is actually a reversion of Humpty Doo due to errors when cultivating it. Humpty Doo is a Chimera, and the growers propagated them by leaves, which caused them to not "bloom through".
The plant in your photo is most likely the pure white sport of Humpty Doo.
Humpty Doo should have double white bloom with lilac/blue edge, whereas the blooms on the clones from were you got them (I saw the other plants), are single and white.
Is it OK if I move this to the generic entry? Thanks.
