Various plants, below, that you can use to regrow food from what you already have! Great way to recycle and SAVE, right?
Use the links below for more info on each vegetable and fruit.
Cabbage: Same as celery
Carrot tops (this is a plant, the carrot itself will not re-grow)
Leeks: same as green onions
Romaine Lettuce: Same as celery
Note that the plant that grows from carrot tops will still put down roots and grow seeds. The seeds can then be used to grow carrot plants that will bear edible carrots!
