is a small to medium-sized woody plant
. Unlike Herbaceous plant
, shrubs have persistent Wood
stems above the ground. They are distinguished from
by their multiple stems and shorter height
, and are usually under 6 m (20 ft) tall.
Plants of many species may grow either into shrubs or trees, depending on their growing conditions. Small, low shrubs, generally less than 2 m (6.6 ft) tall, such as lavender
and most small garden varieties of
, are often termed "
Shrubs are very bushy like beards
Use in parks
An area of cultivated shrubs in a park
or a garden
is known as a shrubbery
When clipped as topiary
, suitable species or varieties of shrubs develop dense foliage
and many small leafy
growing close together.
Many shrubs respond well to renewal pruning
, in which hard cutting back to a "Living stump
" results in long new Plant stem
known as "canes". Other shrubs respond better to selective pruning to reveal their structure and character.
Shrubs in common garden practice are generally considered flowering plant, though some smaller Pinophyta such as mountain pine and common juniper are also shrubby in structure. Species that grow into a shrubby habit may be either deciduous or evergreen.
, a shrub is more specifically used to describe the particular physical structural or plant life-form
of woody plants which are less than high and usually have many stems arising at or near the base.
For example, a descriptive system widely adopted in Australia is based on structural characteristics based on life-form, plus the height and amount of foliage cover of the tallest layer or dominant species.

For shrubs high the following structural forms are categorized:
dense foliage cover (70–100%) — closed-shrub
mid-dense foliage cover (30–70%) — open-shrub
sparse foliage cover (10–30%) — tall shrubland
very sparse foliage cover (<10%) — tall open shrubland
For shrubs less than high the following structural forms are categorized:
dense foliage cover (70–100%) — closed-heath or closed low shrubland—( North America)
mid-dense foliage cover (30–70%) — open-heath or mid-dense low shrubland—( North America)
sparse foliage cover (10–30%) — low shrubland
very sparse foliage cover (<10%) — low open shrubland
