The answer to 'what is shrub' is a woody, perennial plant that is smaller than a tree. Shrubs are typically multi-stemmed and grow between 2 to 15 feet tall. They are often used in landscaping to provide structure, texture, and year-round interest in gardens and yards. Shrubs can be evergreen, deciduous, or a mix, and come in a wide variety of shapes, sizes, and colors to suit different design needs.
Shrubs serve many functions in the landscape, such as providing privacy, defining borders, adding visual interest, and attracting wildlife. They can be planted as foundation plantings, hedges, accent pieces, and more. Proper shrub selection, placement, and care is important to ensure they thrive and fulfill their intended purpose in the landscape.
