Christine, you'll love Whole Foods (or as the locals call it, "whole paycheck"). We are close to the one downtown, and love that you can park underground, take the elevator up, shop, check out, and drive up to street level to pick up your groceries at the door. Or you can take the escalator down to the parking area with your grocery cart. That I haven't tried yet! Too clutzy.
It is a little pricey on the Internet, I think. I plant my gingers in partial shade. A couple wind up in full sun late afternoon and they do fine, but I won't risk it with most of them.
Holly, I hope you're successful finding it. In an international market, you should ask the produce people what might grow from seeds also. I found many tropical plants, like variegated tapioca, that could be grown from the roots that some people use as a food source.
