It's an Alocasia macrorrhizos. They like a lot of water, but still make sure the drainage is good. They don't sit in water as much as Colocasias can. They also prefer full sun but can cope with a little shade. So if it stays indoors most of the time you should keep it in the brightest area you can. The way yours has grown the temperature must be okay. They are grown for food, especially in Fiji, but most probably also in southern China.

It might be nice, as an education for the rest of us, to let us in one what those plants turned out to be, and to leave the pictures posted. Otherwise, posts like these end up being pretty just waste the time of people who look at them after your personal mystery is solved.

Looks like an asiatic lily but don't know the variety. Try looking at some lily galleries to see if you can match it. www.plantlilies.com www.lilynook.mb.ca

This looks exactly what I have! Oriana from Brent & Beckys bulbs. They smell great, they are called orienpets they are orientals crossed with trumpets. I had to move mine late in the summer, I hope they bloom again for me this summer.
