Lemon Grass

Common Name:
Lemongrass

Description:
Lemongrass (Cymbopogon citratus) is a fast-growing, clump-forming tropical grass widely valued for its citrus-scented leaves and stems, which are used in cooking, herbal teas, and natural remedies. This evergreen, ornamental grass thrives in Melbourne's warm months and dies back slightly in winter but rebounds quickly in spring. It features long, slender green blades that arch gracefully, forming a dense, fountain-like habit. Lemongrass prefers a full sun position and well-drained soil enriched with organic matter. In Melbourne, it grows best when planted after the last frost and benefits from protection or mulching during colder months. The plant is highly aromatic, and its thick, juicy lower stalks are harvested for culinary use, particularly in Thai, Vietnamese, and Indian cuisines. It's also a natural insect repellent and makes an excellent companion in edible gardens. Low-maintenance and drought-tolerant once established, Lemongrass is a productive and attractive addition to herb and ornamental beds alike.
