I do not think this is A. odora variegata, it is almost certainly A. macrorhizza variegata. But, it doesn't matter, the conditions for both are virtually the same. ALocasia will not stay 'up' in the conditions you are describing that you keep yours in. They will go dormant from #1 lack of light and #2 cold temps. And if you are lucky, and do not water, the rhizome will not rot. If you have to store it in those conditions in winter, it will probably never attain the status that it had before it declined. It would be much better if you could try and keep in in a warm place, and maybe in a window? Where it gets some light? Even if it goes dormant in those conditions, it would be better than in a cold basement. ALocasias do not like cold temps. Below 60 for a prolonged period sets them up for dormancy and loss of the mother tuber. Then you have to be satisfied with offsets.
