A shrub is a woody plant, with multiple stems and usually less than 3 meters (10 feet) tall.
They are generally smaller and bushier than a tree, but larger than a bush (plant). Shrubs generally have dense foliage and many small leafy branches growing close together, giving the appearance of being a giant bush with a trunk.
Common shrubs include blueberries, honeysuckles, many willows and alders.
