Subshrubs are small, woody plants that are less than three feet tall and do not grow very tall. They are also known as semi-shrubs, dwarf shrubs, and low-growing shrubs. Some other synonyms for subshrubs include bushlets, undershrubs, and shrublets. These plants are usually hardy and can survive in tough soil conditions. They add a unique texture and shape to a garden and look especially striking when paired with taller plants or trees. Subshrubs can be found in a wide variety of species and can be used to add color and interest to a garden bed or border.
