Kashmir's economy is centred around Agriculture, like that of Pakistan. Traditionally the staple crop of the valley was Rice, which formed the chief food of the people. In addition, corn, wheat, barley and oats were also grown. Given its temperate climate, it is suited for crops like Asparagus, Artichoke, seakale, broad beans, scarletrunners, beetroot, cauliflower and cabbage. Fruit trees are common in the valley, and the cultivated orchards yield pears, apples, peaches, and cherries. The chief trees are deodar (National tree of Pakistan), firs and Pines, chenar (State tree) or plane, Maple, birch and Walnut, apple, cherry.
