Overwintering Xanthosoma and A. 'Hilo Beauty'
So, while we're on the subject of overwintering...
How about X. 'Lime Zinger' (presently in a pot outdoors) and Alocasia 'Hilo Beauty' (ditto)
I have both an unheated basement and a cool greenhouse available, though would prefer to store tubers/rhizomes/bulbs rather than keeping plants alive.
