|Caladium 'Frieda Hemple'|
Caladiums are tropical plants, reliably cold hardy in USDA climate zones 10 and 11. However, they may survive mild winters in USDA climate zones 8 and 9. The best way to be sure they survive is to dig them before first frost. Carefully pull the plants. Keep the roots and soil intact, and store in a cool, dry place for a couple of weeks, allowing the roots and soil to dry. After drying, trim off the stems, and brush remaining soil from the tubers. Store them in a paper bag partially filled with dry peat moss or vermiculite in a cool, dry place over winter.
