Hedge plants are a type of plant used to create a boundary or divide a space. Yews (4 letters) and SHRUBS (6 letters) are two common types of hedge plants. Yews are evergreen trees that can grow up to 40 feet tall and have dark green, needle-like leaves. SHRUBS are woody plants that are usually shorter than trees and have multiple stems. They are often used as hedges because they can be easily trimmed and shaped.
