Thanks to GregN, he agreed to part with a couple of citrus he brought in from Stan McKenzie. Gregs' a great guy and always willing to help out. A public thanks to Greg Neil of North Vancouver, Canada.
Any info on these is greatly appreciated. Apparently not much is available on Sudachi, Yuzu however is more widely grown.
Cheers, Barrie (Vancouver Island).
