Cymbopogon Citratus - The Lemon Grass Plant is a tropical attractive clump-forming grass that grows upright and slightly arching. It has light-green foliage that is strongly lemon-scented. A tender perennial that can be over-wintered in a sunny window. 

Lemongrass contains citronella, a natural oil that repels mosquitoes. Plant multiples in containers for maximum benefit on porches, patios, gazeboes, etc. Poisonous to: Dogs, cats: Stomach upset 

The plants grow in dense clumps up to 6 feet in diameter, with leaves up to 3 feet long. They require warm, humid conditions in full sun to thrive. The coarse, strap-like leaves are ½-1” wide, finely serrated on the edges (rough enough to cut the skin), tapered at the end, and have gracefully drooping tips.  It is not as attractive as many other ornamental grasses but clumps can develop into imposing specimens. Plants will flower with a branched cluster of stalked flowers but usually not when grown as an annual. These are not ornamental and rarely set seed.

Grow lemongrass in containers or as an annual during the growing season. Plant in full sun in moist, loam soil, preferably with high organic content. Place outside as soon as the danger from frost is past. Clumps will grow slowly until the heat and humidity of summer arrives then the plants will increase in size dramatically. This plant requires a great deal of water, so water regularly if rainfall is sparse.
