11 herbs you can grow with just water

Green onions, or scallions, are incredibly easy to grow in water and can be harvested continuously. Simply take the white root ends of store-bought green onions and place them in a glass with enough water to cover the roots. Place the glass in a sunny location, and you’ll see new green shoots emerging within days. Change the water every few days to keep it clean. As the green onions grow, you can snip off the tops for use in cooking, and they will continue to regrow.
