Planting different types of trees adds interest to the landscape and provides color and shade. Trees can also improve property values, make your outdoor space more enjoyable and provide habitat for birds. The Weeping Willow Tree is treasured for the movement, elegance and style it adds to landscapes. This fast-growing tree is also a good shade tree. The Golden Chain Tree offers year-round interest with decorative bark, clusters of golden yellow flowers and lush foliage. A low-growing tree, it's a good choice for smaller spaces. Some factors to consider when buying trees are their mature height and spread, hardiness zone, soil and water requirements, and foliage color.
