Tropicals & Tender Perennials: What do I do with this Amorphophallus bulb?!, 1 by Plants4myPots

Oh, BOY! I'm digging into a whole new family of plant!!!

So my lovely neighbor dug this little bulb out of her large and (seemingly empty) planter and gave it to me as a moving away present. She knows it's an amorphophallus - but not which particular one, and said it's tropical, so it should do really well when I get to Florida and pot it up.

What in the world do I do with this bulb? Right now, it's no more than 1.5" (or 3.5 cm) in diameter. But I've seen pictures of bulbs that are well over 6" (15cm), and I'm guessing that these bulbs just start small and will get bigger every year as they grow and make more bulbs. I have no idea what the rest of the bulbifer under the dirt in my neighbors planter looks like...

I guess what I need to know first,

1. What kind of medium/soil mix should I plant it in?
2. How big does the pot really need to be?
3. How deep do I plant it?

I'm so excited!! Thanks in advance for the much-needed advice!
