Toni, I guess it's all a matter of growing conditions. I've bought about three dozen Charismas over the last 25 years and every single one has suffered so severely from black spot that they rarely have any foliage at all. It never affects the gorgeous blooms, however.
Unfortunately, Charisma's also irresistible to gophers, so almost all of those three dozen are gone. I think I have three left, maybe four. Sue bought me a gorgeous Charisma tree rose last year and that one's planted in a cage, so it's here to stay.
Minuette could easily be my favorite too, Evey. It's such an appealing little rose.
