I am now interested in permaculture for the main reason that I am now partially disabled. I managed to get hold of the fabled perennial kale and it was the best thing I ever did. I have grown it for a few years now and I'm still impressed with it. It grows fast and as long as I keep my enviromesh over it then it's trouble free. It reaches 3ft tall and wide in one growing season. It's easy to propagate from cuttings as well. If anyone wants a plant then get in touch.
