A shrub or bush is a horticultural rather than strictly botanical category of woody plant, distinguished from a tree by its multiple stems and lower height, usually less than 6 m tall.
A large number of plants can be either shrubs or trees, depending on the growing conditions they experience.
Small, low shrubs such as lavender, periwinkle and thyme are often termed subshrubs.

A natural plant community dominated by shrubs is called a shrubland.
The word bush can also refer to a type of plant community, as in the Australian bush.
This is often characterised by scrubby, open woodland and is a generic term for Eucalyptus dominated woodland in particular.

An area of cultivated shrubs in a park or garden is known as a shrubbery. When clipped as topiary, shrubs generally have dense foliage and many small leafy branches growing close together.
Many shrubs respond well to renewal pruning, in which hard cutting back to a 'stool' results in long new stems known as "canes".
Other shrubs respond better to selective pruning to reveal their structure and character.

Shrubs in common garden practice are generally broad-leaved plants, though some smaller conifers such as Mountain Pine and Common Juniper are also shrubby in structure.
Shrubs can be either deciduous (sheds and renews leaves annually) or evergreen.
