Glen ~ that is the one I was thinking of. Yes, I had heard the origin of the name. I've had birds spread those seeds and now have a small patch of them growing on the edge of my driveway. Probably while the birds were perched on the power line. Thanks for sharing the pretty photos and the information.
Tom, I don't think their roots would be winter hardy in your area but you could keep it in a container or start from seed. I know many in the US grow it simply for the ornamental factor rather than a food source. If you notice the foliage in Glens' early photo, it is very pretty and distinctive. I haven't saved seeds from the wild ones but perhaps I should do so.
