Lemongrass is a tropical herb packed with strong citrus flavor. The lemon taste is prized in Asian cooking, as well as in teas, sauces, and soups. In the garden, lemongrass forms a tall, grassy clump 3 to 5 feet tall. Its appearance rivals that of many ornamental grasses and can easily fulfill a similar role in the landscape.
Due to its tropical nature, lemongrass usually only survives winters in zones 8 and warmer. In other areas, try growing lemongrass as an annual in planting beds or tucked into pots. This citrus-flavored grass overwinters well in a dormant state in a cool, dark spot indoors, or you can grow it as an indoor herb through winter in colder zones.
Harvest lemongrass for its bulbous stem bases, rich with lemony flavor, or clip leaves for infusing tea and soup stock.
