A "bush" is a type of plant that is typically smaller than a tree and has multiple stems or branches. Bushes can vary in size, shape, and type, and they often have leaves, flowers, or fruits. Common examples of bushes include rose bushes and boxwood. They are often used in gardens and landscaping for decoration or privacy. Bushes play an important role in ecosystems by providing habitat and food for various animals, including birds and insects. They can also help prevent soil erosion and improve air quality. Many bushes are hardy and can thrive in different climates, making them a popular choice for gardeners.
