What are Trees & Shrubs?
A tree usually has one stem, which at some height has branches. A shrub can have multiple stems from the bottom up. Usually, bushes do not grow as tall as trees, very often they are less than 1–2 m tall. Very many plants can be either shrubs or trees, depending on the growing conditions.
A shrub or bush is a small- to medium-sized perennial woody plant. Some shrubs are deciduous and others evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6 meters (20 feet) tall.
