This is one impressive beastie which will have your neighbours peering over the fence all Summer. There are many variations of Alocasia and you should make sure you get the right species as a lot of places label any of them how they please.
I have experimented with this plant somewhat and can safely say that it hates full sun. It does like it hot however, but sweaty hot rather than dry hot. Plant it out in the Summer and bring it in for the Winter.
I subjected mine to an unheated greenhouse 2 Winters ago that went down to -4c inside. The foliage melted (as expected) and I was left with a stump. I left it in the greenhouse over Summer and it shot back through the same stump. So it looks like it is pretty hardy to low minus figures at least !!!!
It likes to be fed and watered a lot in the Summer. One of it's funky features is the way it can shrug off water. Mist it, spray it, throw a bucket of water over it... this plant sheds every drop... it is awesome to watch :D
