Lemon Grass (Cymbopogon citratus) takes on dual duty as a bright green ornamental grass that you can eat! Quickly becoming one of the most popular grasses for the landscape, Cymbopogon ciratus, can grow up to 5' when planted in a sunny spot. Use Lemon Grass (sometimes spelled as one word: Lemongrass) next to the patio or deck where its citrusy scent naturally repels pesky mosquitoes. Harvest it and add to teas or season meals, and serve to your friends who won't believe they're eating your beautiful garden!
