The primary purpose of a shrub is to provide habitat and food for wildlife, stabilize soil, and enhance landscape aesthetics. Shrubs are versatile plants that can serve multiple ecological functions, including serving as windbreaks, erosion control, and privacy screens. They are typically shorter and bushier than trees, making them ideal for gardens and landscapes. Additionally, many shrubs produce flowers and fruits, attracting pollinators like bees and butterflies, contributing to biodiversity in an ecosystem.
