Before you throw out or compost your leftover vegetable kitchen scraps, you might be able to regrow some of them for free food with this cool new Kikkerland Terracotta Regrower. Green onions, potatoes, celery, romaine lettuce, fresh herbs, and much more can easily be regrown from their chopped off root ends that normally get tossed. Just fill up a cup or mason jar with water, insert these terracotta regrower planters, insert the vegetable root ends, and put them in a sunny spot. In no time you should have all new growth that can eventually be transplanted back to your garden or planter. With green onions, you never need to buy more. Just keep the ends in water and snip off what you need... they'll keep regrowing back. This set makes a unique gift for vegetables lovers and cooks with a green thumb.
