Trees:
* Single, tall, and central trunk: Trees have a single, dominant trunk that grows upright and typically reaches a height of at least 13 feet (4 meters) at maturity.
* Defined canopy: They develop a distinct crown or canopy of branches and leaves high above the ground.
* Long lifespan: Most trees live for many decades or even centuries.
Shrubs:
* Multiple stems: Shrubs have multiple stems that branch out from the base of the plant.
* Lower height: They typically grow to a height of less than 13 feet (4 meters).
* Bushier shape: Shrubs generally have a more rounded or spreading growth habit.
So, to answer your question directly:
* Trees have a single, tall, central trunk that shrubs lack.
However, there are exceptions and overlapping characteristics:
* Some shrubs can grow quite tall, blurring the line between the two.
* There are also trees like weeping willows that have multiple stems that can make them appear shrub-like.
Ultimately, the distinction between trees and shrubs is not always clear-cut, and it can depend on the species and the way it is grown.
