Suited to warm or mild dry climates only, Cypresses are long-lived and fast-growing trees. These evergreens have a variety of shapes and forms. Some are dense and bushy, while others are flat-topped or pyramidal. All have cones, and their fragrant foliage is generally dark green. Use singly or massed as windbreaks or screens. Water during dry spells in the first few years. Older trees are drought-tolerant.
