About Lemongrass

Lemongrass is a tropical grass used throughout Southeast Asian, Indian, and Caribbean cooking. The fragrant stalks flavour curries, soups, and teas. In cold zones, grow as a container plant and overwinter indoors.

In cold zones, start indoors 8 weeks before last frost in a large pot. Bring indoors before frost. Divide clumps every 2-3 years. Harvest outer stalks 12 inches tall. Loves heat and full sun.
