I'm really interested in this thread. I have a kale plant that's 3+ years old I've brought indoors for winter. I planted it back outside yesterday. It's about 5.5 feet high and spiraling so much I have to support it with braces. Once it adjusts to being back outside, I've been toying with the idea of essentially clipping it in half, rooting the top of and propagating pieces of that plant over time. And THEN, grafting another plant into the original stem of the kale plant. Any suggestions? I'll document it. Maybe a tall kale stalk with purple cabbage on top?
