Lemongrass is a tropical perennial grass native to India and Southeast Asia, valued for its strong citrus aroma and flavor. It is widely used in culinary, medicinal, and ornamental applications. The plant features tall, slender, bright green blades and grows in dense clumps, reaching up to 48 inches in height. It contains essential oils rich in citral and geraniol, making it popular for perfumes, insect repellents, and therapeutic remedies. While frost-sensitive, lemongrass can be grown as an annual in cooler regions or overwintered indoors.
