I am no expert on trops, but Charlies Pride looks exactly like Miami Rose to me.
Same goes for Blue Aster...there are a lot of look a like moptops out there, at least to me, being no expert.
Avalanche looks different and new to me. Unique...I like it best out of all of them because to me it is the most unique.
To me it is a 3 color lily, from pink, to white, to periwinkle-blue.
