Andropogon schoenanthus.

Botanical name: 

Andropogon schoenanthus Linn. Gramineae. Camel's Hay. Geranium Grass. Lemon Grass. Oil-Plant.

Asia, African tropics and subtropics. This species is commonly cultivated for the fine fragrance of the leaves which are often used for flavoring custard. When fresh and young, the leaves are used in many parts of the country as a substitute for tea and the white center of the succulent leaf-culms is used to impart a flavor to curries. The tea made of this grass is considered a wholesome and refreshing beverage, says Wallich, and her Royal Majesty was supplied with the plant from the Royal Gardens, Kew, England.
