I posted a couple of weeks ago about having planted peas inside of split rims as a sort of raised bed. Those pea plants will be left to grow so that we can eat the peas. I also planted a window box with peas with the intention of eating the shoots instead of letting the plants mature. I had watched this on TV last year and until that time didn't know the shoot was edible. They're very edible, very delicious, are quick to harvest (about 3 weeks), will continue to grow for further harvests and make a wonderful addition to salad.
I love them so much that I've decided to plant them indoors this winter to enjoy as a fresh out of season green, along with bean and seed sprouts, mmmmmm.
