I don't trust it to be cold hardy. I've grown it for about four years and it spends winters
inside a garden room. The leaves are the size of a large outstretched hand.

"Alocasia are distinctly exotic and tropical plants that are increasingly becoming popular as houseplants.[3] The hybrid A. × amazonica has gained the Royal Horticultural Society's Award of Garden Merit. They are typically grown as pot plants, but a better way is to grow the plants permanently in the controlled conditions of a greenhouse. They do not do well in the dark and need good lighting if inside the house. They should be cared for as any other tropical plant with weekly cleaning of the leaves and frequent fine water misting without leaving the plants wet.

Unfortunately, they rarely survive cold winters, or the dryness of artificial heating, but an attempt to slowly acclimatize plants from the summer garden to the house can help. Once inside the watering period must be reduced and the plants should be protected from spider mites or red spider attack. Alternatively, let younger plants die back to the corm from when the temperature reaches 19 degrees and with some luck this could lead to a rebirth in spring."
