Answer: Your cannas seem to be marching to a different drummer! Typically they will remain dormant when stored at 45-50F. Since yours think it's time to wake up, it would be best to pot them up in containers and water them in. They may continue to grow or they may stop growing and just sit and wait for warmer weather. In any event they need to be protected from outdoor weather until it really is spring outside. After potting them up, keep them near a window but not exposed to bright sunshine (unless you really want them to grow!). If the temperatures in your basement are cool and there's only a little light, they will probably develop slowly. If temps are too warm and light too bright, they will think it is spring and will grow quickly. When the temperatures warm up outside you can put them out, in a shady spot and then eventually plant them in the ground. Good luck with your cannas.
