  According to the botanical preservationists at the National Tropical Botanical Garden, 90 percent of plant and animal species exist in the tropics. The abundant sun and rain of tropical climates allows tropical plants to assume great stature, bear colorful flowers and live for extended periods. A number of tropical plants are suited for growth in the United States, and you can purchase them at nurseries for home gardens.
