Cymbopogon citratus. Lemongrass is one of the herbs many people don't feel they can grow. However, lemongrass grows easily in containers or in-ground and will grow well even in places with shorter growing seasons. The plant is a tender perennial to zone 9. It can be cut and dried for teas, essential oil, or lemongrass soup. Leaves and stalk have a distinct but soft lemon flavor. Lemongrass essential oil is often used in cosmetics, body care, and aromatherapy. Leaves reach up to one meter long.
