A '''shrub''' or '''bush''' is a small to medium-sized [[perennial]] [[woody plant]]. Unlike [[herbaceous plant]]s, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from [[tree]]s by their multiple [[Plant stem|stems]] and shorter [[height]], less than {{convert|6–10|m|ft|abbr=on}} tall.<ref name="LawrenceHawthorne2006">{{cite book

Others use {{Convert|10|m|ft|abbr=on}} as the cutoff point for classification.<ref name="Allaby2019" /> Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between [[Perennial plant|perennials]] and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond 70. On average, they die after eight years.<ref>{{Cite web |date=2014-02-27 |title=Life Spans of Small Trees and Shrubs |url=https://temeculalandscapeconstruction.com/life-spans-of-small-trees-and-shrubs/ |access-date=2022-04-29 |website=McCabe's Landscape Construction |language=en-US}}</ref>

[[Shrubland]] is the natural landscape dominated by various shrubs; there are many distinct types around the world, including [[fynbos]], [[maquis shrubland|maquis]], [[shrub-steppe]], [[shrub swamp]] and [[moorland]]. In gardens and parks, an area largely dedicated to shrubs (now somewhat less fashionable than a century ago) is called a [[shrubbery]], shrub border or shrub garden. There are many garden [[cultivar]]s of shrubs, bred for flowering, for example [[rhododendron]]s, and sometimes even leaf colour or shape.

Compared to trees and herbaceous plants, a small number of shrubs have culinary usage.{{citation needed|date=April 2024}} Apart from the several [[berry]]-bearing species (using the culinary rather than botanical definition), few are eaten directly, and they are generally too small for much [[timber]] use unlike trees. Those that are used include several perfumed species such as [[Lavandula angustifolia|lavender]] and [[rose]], and a wide range of plants with medicinal uses. [[Camellia sinensis|Tea]] and [[Coffea|coffee]] are on the tree-shrub boundary;<ref>{{Cite web |last=Clayton |first=Liz |title=Is The Coffee Plant A Tree, Bush, Or Shrub? |url=https://sprudge.com/is-the-coffee-plant-a-tree-bush-or-shrub-181869.html |access-date=2022-04-29 |website=sprudge.com |date=20 October 2021 |language=en-US}}</ref> they are normally harvested from shrub-sized plants, but these would be large enough to become small trees if left to grow instead.

==Definition==
Shrubs are perennial woody plants, and therefore have persistent woody [[Plant stem|stems]] above ground (compare with succulent stems of [[herbaceous plant]]s).<ref name="Allaby2019" /> Usually, shrubs are distinguished from trees by their height and multiple stems. Some shrubs are [[deciduous]] (e.g. [[Rhaphiolepis|hawthorn]]) and others [[evergreen]] (e.g. [[holly]]).<ref name="Allaby2019" /> [[ancient Greece|Ancient Greek]] philosopher [[Theophrastus]] divided the plant world into trees, shrubs and herbs.<ref name="Bremness1994">{{cite book |last1=Bremness |first1=Lesley |title=The complete book of herbs |publisher=Viking Studio Books |isbn=9780140238020 |page=8 |url=https://books.google.com/books?id=VqfnrH-W2kwC|year=1994 }}</ref> Small, low shrubs, generally less than {{Convert|2|m|ft|abbr=on}} tall, such as [[lavender]], [[Vinca|periwinkle]] and most small garden varieties of [[rose]], are often termed as [[subshrub]]s.<ref name="Fischer1990">{{cite book

Most definitions characterize shrubs as possessing multiple stems with no main trunk below.<ref name="Allaby2019" />  This is because the stems have branched below ground level. There are exceptions to this, with some shrubs having main trunks, but these tend to be very short and divide into multiple stems close to ground level without a reasonable length beforehand. Many trees can grow in multiple stemmed forms also while being tall enough to be trees, such as [[oak]] or [[ash (tree)|ash]].<ref name="Allaby2019" />

==Use in gardens and parks==

An area of [[Plant cultivation|cultivated]] shrubs in a [[park]] or a [[garden]] is known as a [[shrubbery]].<ref name="Whitefield2002">{{cite book

Shrubs in common garden practice are generally considered [[flowering plant|broad-leaved plants]], though some smaller [[Pinophyta|conifers]] 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]].<ref>{{cite book|url=https://books.google.com/books?id=vlDxSBGB0cYC&q=shrub+deciduous+or+evergreen|title=Popular Deciduous and Evergreen Trees and Shrubs|first=Franklin Reuben|last=Elliott|date=1 November 2008|publisher=Applewood Books|access-date=19 December 2017|via=Google Books|isbn=9781429012904}}</ref>

In [[botany]] and [[ecology]], a shrub is more specifically used to describe the particular [[Canopy (biology)|physical canopy structure]] or [[plant life-form]] of woody plants which are less than {{convert|8|m|ft}} high and usually multiple stems arising at or near the surface of the ground. 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 [[Dominance (ecology)|dominant]] [[species]].<ref>Chris Paul (2024). [https://shrubradar.com/best-evergreen-shrubs-for-the-front-of-your-house The Best Evergreen Shrubs for Front Yards]. Shrubs Radar, a website all about shrubs.</ref>

For shrubs that are {{convert|2|-|8|m|ft}} high, the following structural forms are categorized:
* dense foliage cover (70–100%) — '''closed-shrubs'''
* mid-dense foliage cover (30–70%) — '''open-shrubs'''
* sparse foliage cover (10–30%) — '''tall shrubland'''
* very sparse foliage cover (<10%) — '''tall open shrubland'''

For shrubs less than {{convert|2|m|ft}} high, the following structural forms are categorized:
* dense foliage cover (70–100%) — '''closed-[[heath (habitat)|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'''
