Did you know veggies can regrow from their stumps? I was surprised to learn this a while back, and even more surprised by how fast they sprout. These scallions -- as tall as their papery skins at the start -- added inches to their height in just a few days. Amazing. At some point, regrown vegetables need to be retired, since without the nutrients only soil can bring they lose vitality over time. Until then, through multiple rounds of growth, though, they bring delicious flavor and pretty garnish to home-cooked meals, and make a handy, and supremely easy to maintain, kitchen garden item.
