If you want to try something for the fun of it and not drop too much money at a garden center, head to the local grocery store that carries some international foods. Go to the produce section and look for "Taro root."

J'yup, for a paltry $1.49/lb. or so you can have yourself some fresh taro root. Now .... what you'll get as a resulting plant is the fun part: you just don't know until it comes up. And being this late in the season, you may never really get a hard ID on it before the first frost hits. All the same, dig 'em, store 'em in the root cellar, and watch out for next season.

Be patient, though ... mine were somewhat refrigerated and took a couple weeks to pop up despite being mid summer. Really loose, well drained soil that it constantly watered will bring them up the quickest.

Just for reference, that's a 54" TV no mre than a foot or so behind this Taro and was taken over a month ago. It has spent this year out of bright light and in a very cool air conditioned house and it's still rather happy.
