Lemongrass

Lemon grass is a potent lemon-citrus herb. Common as a seasoning in Asian cuisine, it also works great as a tea. Lemongrass tea is thought to be a home remedy for certain conditions and lemongrass essential oil has many homeopathic benefits as well. 

For gardeners looking to get the most bang out of their real estate buck, edible landscaping fills two desires, increasing curb appeal and getting fresh herbs. It can be added as a flavoring agent to tea and cakes.
