Thanks for the post concerning the OCA. I've been racking my brains for months about this root. It was featured on a gardening program on the BBC several months ago, and I didn't catch it's name. Most certainly will give it a try. Let's just hope that next year will be a little dryer and we will have better look with it. I hear that it is a great source of starch.
