I have tried it a couple of times now, with very limited success in terms of germination and growth. Granted, both years that I tried it we experience pretty severe drought, so I am not sure that my experiences was very reliable. Reading Skip's post above...maybe in addition to the drought conditions, my soil wasn't what it needed to be?? FWIW, I did try it in two different plots and I have successfully grown many other plots in those spots over the years.
I have a neighbor up the road that thinks that it is the cat's meow though, he swears by it.
