You can buy nice-sized fresh Chinese (SHAN YAO) or Japanese (NAGAIMO) yam roots from an Asian grocer. I've had success planting NAGAIMO from the grocery store. Just look for a nice-sized, fresh-looking chunk. They aren't expensive either. Asian grocers or coops are great places to find plant starts. Other things that I've successfully planted are: ginger (organic from Costco); lemongrass, tumeric, chayote, Jerusalem artichokes, taro (from my regional store chain that that stocks more uncommon stuff); water chestnuts (Asian grocer).
I've also had a lot of failures but the monetary outlay is low so I'm willing to try many things.
I'm growing tropical Yams from one bought at an international market in the city and they're doing great. Just cut the Yam into chunks, dusted with ash, and planted in composty soil. They waited until it got nice and warm before they sprouted, but once planted out they are growing quickly. My Chinese Yams grown from bulbils, on the other hand, are tiny and slow. Not sure why. Maybe because the bulbils are so small compared to the chunks.
