Not just the Three sisters

Off the top of my head I can’t think of anything. But I like the idea. Going to definitely try the 3 sisters when I have some raised beds in place. Really like the Idea of sunflowers in the mix as well. Love sunflowers.
Going to have a think about other possibilities, while I’m digging today.

I thought about the 3 sisters then realised that the optimum  planting distances (if you pay attention to such things) we're much greater than I was able to accommodate at the time.
