Trees & Shrubs

Trees and shrubs are woody plants, they are also perennial but do not die back each year. Many trees and shrubs lose their leaves each autumn, making them deciduous, while some retain their leaves and are called evergreen. Trees generally have one main stem and grow to be more than twelve feet tall. Shrubs have multiple main stems and are usually shorter than twelve feet.
