Shrubs and trees are sometimes confused. However, shrubs always have many stems which branch at or near the ground level, while trees usually have a distinct stem or trunk.
Trees grow throughout the world from the far north to the far south.
The tallest trees are the California redwoods which reach heights of about 350 feet. The smallest trees are birch and willows in the arctic tundra which grow only a few inches tall. The biggest trees are not necessarily the oldest. Canyon Creek Scenics can make deciduous trees on a special order basis. Some of the pictures on this site look like real trees.
