Garlic scapes are the flower stems of hard neck garlic. Cut them off to promote bulb growth. Boil, steam, sautee, great with a little butter, salt and pepper.
Basil. Pinch off the top couple of leaves, 2 branches will develop. The more you pick, the fuller the bush becomes. I like it whole as a salad green.
Lots of herbs can be cut and thrive from the abuse: Oregano, marjoram, thyme, fennel, dill, cilantro, sage, and rosemary to name a few.
Fiddleheads are the tender young shoots of the ostrich fern. Nothing better than fiddleheads.
