Deebie, I have Hilo Beauty here and it does go dormant every winter even in Florida! As soon as we consistently are getting nights in the low 50's it gradually disappears. Jumps right back up in the spring. These have been in the same pot for 3 years. I just add timed release fert in the spring, and again in late May, and they go crazy all summer. Think I will divide them this year after they die back. There must be a lot of tubers in that pot by now.
They act like Caladiums, but there is still some debate as it was sold as an Alocasia until just recently. It's definitely taller and has bigger leaves than any of my Caladiums.
