Habitat: Lemon grass is endemic to Southeast Asia, particularly India, Sri Lanka, the Philippines, Thailand, and Vietnam.

It has been introduced in many US states, including California and Florida; and in South America, particularly Brazil.

Description: Lemon grass is a tender perennial of the grass family and resembles many of its members in the long, upright blades, but with leaves at the ends, and growing in clumps.

These blades are sharp, denser than most grasses, with a thick solid, almost bulb-like base of a few inches, and has a height of three to six feet. Blades are deep nearly bluish-green in color, white near the thick, clumpy stems, and branch from this bulb in dense white growths. When cut they have the appearance of a scallion.

Flowers are rare on lemon grass plants, but when they do bear, they are large heads with false reddish-brown spikes.

Plants reach around five feet in height and four feet in breadth. The telltale fragrance of this lemon-scented plant is due to the presence of essential oils in the tube-like cells.

Plant Parts Used: Leaves and Oil (medicinally). Leaves and Stem (culinary).
