The temperatures may be playing with the colors, height, and blooms size?
There is no evidence to suggest yet it is not Heavenly Thunderbird.
The only way would be to cut a branch off that has big fat buds and take it indoors to bloom where it is warm. You will see what the "real" colors are supposed to be.
But I like these colors way better than those of Heavenly Thunderbird.
A keeper for sure.
