Gardens Illustrated podcasts
Gardens Illustrated, the BBC-published British gardening magazine, offers some of the best gardening podcasts I've heard. Click this link to get to the GI podcast webpage. I particularly recommend the GI 2006 lecture, really more a long conversation with Anna Pavord, Beth Chatto, and Dan Pearson.
I've recently acquired an ipod, so I'll add posts to other outstanding podcasts, if I find them. Most podcasts from the good old USA don't seem to compare.
