Purslane (Portulaca oleracea), "companion planted" with elephant ear
A couple of years ago I was at a nice restaurant, eating a fancy salad, when I realized that I was eating weeds. Yes, there was purslane in my salad and it was the exact same weed I'd been pulling out of my garden beds and potted plants for years. That's when I realized that if they can put it in a fancy salad, I can eat the damn thing from my own back yard. And that's exactly what I've been doing.
