Ive never had experience but I know of this thing called tissue culture. You will have a high production rate and since this is probably a hard to propagate
plant, tissue culture would be good for it. Heres a description and a good place to buy a set:
http://en.wikipedia.org/wiki/Plant_tissue_culture http://www.kitchenculturekit.com/kit.htm It sounds hard to do, but its not supposed to be. Ive researched a lot on this but I havent tried it YET. I dont want to sound like a know it all or anything but dont take my word for it. I hope to get that kit above soon. People Ive talked to have reported great success with it.
