Lemon grass has so many uses! One is to keep bugs away. It also grows to a very reasonable size. You can cut a piece, boil it and and have lemongrass tea. Lemongrass grows back even if you cut it off a leaf. When you buy lemon grass at the store, you can take about an inch on the bottom and let it sit in water for a week and look at it`s growth!
