thanks dry gulch. i'd found that source too, but they don't ship over the summer.
amazingly, i finally found some locally. it cost an arm and a leg, but i figured i didn't have to pay for shipping, and..... well.... no other excuses come to mind. basically, i just wanted it really really badly!

For european ginger plants try www.bridgewatergardens.com.
