Lemon Grass

Frost Tolerance: Quite tender in Phoenix and Las Vegas

Sun Exposure: Full sun to light shade

Origin: C. flexuosus: India, Sri Lanka, C. citratus: Indonesia, Malaysia

Growth Habits: Perennial grass, leaves 3' to 6'.

Watering Needs: Regular water in Summer

Propagation: Division of clumps

Culture:
The Lemon Grass needs protection from frost in winter. To be safe, it might be a good idea to keep a division in a warm area over winter. The clump at my house has been growing on the north side of my house for 3 years, in a shady area. It is protected from frost by overhead vegetation. My feeling is that it is a fairly tough plant that is doing well without much care.
It will grow much better with regular watering in summer, takes well to irregular watering in winter. A small clump of Lemon Grass planted in spring will give you a large scented clump by fall to harvest. The grass can be used to make lemon tea, lemonade, or Asian cooking.

Propagation:
Propagate by division of clumps in the fall or early spring.
