I planted 3 Hilo Beauty plants last year in my semi-shade garden and they thrived well beyond my expectations. I did not lift them in the fall and now wonder if they will return this summer? Does anyone know? We are z7b to 8 and I've read they are hardy to 7b. I see no signs of life yet but it is quite early. Since I've also read that they could be related to the caladium, I could be in trouble because my caladiums never over-winter in the ground. I hope someone can give me some good news because I'd hate to lose these beautiful plants. Thanks!
