[0002] Shrubs refer to trees that have no obvious trunk and grow in clusters. They are usually short and have a relatively short lifespan. The definition of shrubs is not very strict and is mainly used to describe non-tree woody plants. In botany, shrubs can refer to trees that grow poorly and fail to develop into trees, or they can refer to horticultural plants that are deliberately cultivated into short, clumping plants. Shrubs are also an indispensable plant type in landscaping and are often used in landscape design, environmental protection, and ecological restoration.
