Lemongrass

Lemongrass is a type of herb that grows as long, thin, sharp grassy bushes and smells like lemons. The base of the leaves resembles a scallion, but are much larger and tougher. Lemongrass grows up to six feet and grows ideally in tropical conditions. Lemongrass has culinary and medicinal purposes and insect repellent properties (citronella oil). It is also used in pesticides, preservatives, and antifungal. You can find fresh lemongrass bundles at grocery stores.
