A wonderful herb for herb teas and asian cooking. Use the lower 10-15cm of the fresh stem whole or chopped. Bruise the stems to release the flavour. Tastes good with curries, soups and casseroles. Grows into large bushy clumps which like it quite warm and quite wet. Easily grown in pots handy to the kitchen. Cut back in winter or just leave it for the wild look. Protect from frost. Can be used medicinally or as an insect repellent.  Makes a great barrier plant to keep other grasses and weeds out.
