I think its the same as the 3 i have growing in my garden!!? ( WALES U.K) I had them from tubers, so have no idea which variety they are, but the blooms where a tropical, blood orange..I had them in pots last winter outside & they survived..This year i've left them in the ground, I have not cut them back this winter, will do in late spring on one plant & leave the other.. just to see if the climate required them to be dug up & potted.
GOOD LUCK, IT'S A BEAUTIFUL PLANT ..
I've had really good luck with them--just need to dig & store them each winter.
