Woody perennials are plants that live for multiple years and have a hard, woody stem. Unlike herbaceous plants, which die back to the ground each year, woody perennials maintain their structure and grow larger over time. Common examples include trees and shrubs, which can provide shade, habitat, and beauty in gardens and landscapes. These plants typically undergo seasonal changes, shedding leaves in autumn and regrowing them in spring. Woody perennials are important for ecosystems, as they contribute to soil health, support wildlife, and can help prevent erosion. They are also used in landscaping and forestry for their durability and aesthetic appeal.
