Jerusalem Artichokes, anyone?

I'd like a tuber or two to put in my garden. I've grown them before and yes, I know how they propagate. That's why I only seek a tuber or two. I do like how they taste though, and I'm pretty sure they'll do well for me.

I have for trade:
- hostas
- day lillies
- ostrich fern
- rhubarb (would have to wait until they break ground as I don't have their location well marked.)
- walking onions
- smoking wood (Apple, cherry, maple, walnut, mulberry, box elder, lilac) No, I don;t smoke these - I use them for smoking in my Weber Smoky Mountain.

thanks,
hank
