Abstract from DBPedia
    A shrub (often called a bush) is a small- to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants. Some definitions state that a shrub is less than 6 m (20 ft) and tree is over 6 m. Others use 10 m (33 ft) as the cut-off point. Many species of tree may not reach this mature height because of less than ideal growing conditions, and resemble a shrub-sized plant. However such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in between perennials and trees; some may only last about five years even in good conditions, others, usually the larger and more woody, may live to 70 or more. Shrubland is natural landscape dominated by various shrubs; there are many distinct types around the world, including fynbos, maquis, shrub-steppe, shrub swamp and moorland. In gardens and parks, an area largely dedicated to shrubs (now somewhat less fashionable than a century ago) is called a shrubbery, shrub border or shrub garden. There are many garden cultivars of shrubs, bred for flowering, for example rhododendrons, and sometimes leaf colour or shape. Compared to trees and herbaceous plants, perhaps a relatively small number of shrubs have agricultural or commercial uses. Apart from several berry-bearing species (using the culinary rather than botanical definition), few are eaten directly, and they are generally too small for timber use. Those that are used include several perfumed species such as lavender and rose, and a wide range of plants with medicinal uses. Tea and coffee are on the tree-shrub boundary; they are normally harvested from shrub-sized plants, but these would become small trees if left to grow.
