I haven't yet... but I'm threatening 'Girly Girl', 'Tiger Honey' & 'Brindled Beauty'... maybe 'Coyote Ugly'.
'Girly Girl' has been a good grower, but I have several plicatas in that color range..
'Brindled Beauty' has kind of a "crowned" top (open standards) that i don't care for. The color washes out some as the flowers mature.
'Tiger Honey' looked so unusual when I first saw it many years ago. It's lost it's appeal. It just looks muddy to me in the garden.
'Coyote Ugly'.. other than this charming pattern, that only occurred once, it has the same problems as Brindled Beauty. Not an elegant form. I think I'm just getting over the novelty of broken colors.
