Deciduous trees lose their leaves in the winter and regrow them in the spring, while non-deciduous trees-- also known as evergreens--keep their leaves all year long. Non-deciduous trees are sensible options to use as shade trees, because their leaves provide shelter from sun and rain throughout the year.
Live oak trees grow between 65 feet and 85 feet tall, their branches spreading outward and providing a good amount of shade. These trees produce stiff, dark green leaves that can be narrow or slightly oval. The leaves gradually fall in the spring as new leaves emerge. Live oaks also produce acorns, which attract squirrels and other animals. Valued for the strength, density and hardness of its wood, live oak is a popular construction material.
Tropical banyan trees are native to India, Pakistan and Sri Lanka, but if you live in a southern region of the United States, try planting these exotic trees. Before planting, however, make sure you have plenty of space, because banyans can reach up to 100 feet. Banyan trees have aerial roots known as "prop roots," which hang from branches and take root when they touch the ground, making the tree look like its own forest. These trees produce leaves that grow between 5 and 10 inches long, and inedible, fig-like fruits.
This tall, non-deciduous tree can grow between 50 feet and 150 feet tall. Camphor trees have thick trunks with wide, spreading canopies of leaves that are shiny, green and oval; they also produce waxy black berries. Camphor trees are natives of Asia, but also grow in parts of the United States with warm climates. However, in some areas, such as Florida, the camphor tree can be invasive.
