|synonyms_ref = [1] |}}Cytisus multiflorus is a species of legume known by the common names white broom[2] and white spanishbroom.[3] DistributionIt is native to the Iberian Peninsula. It is better known as an introduced species on other continents, including Australia and North America, where it has become a weed in agricultural land and an invasive species in natural habitats. DescriptionCytisus multiflorus is a shrub growing up to {{convert|3|m}} or {{convert|4|m}} in sprawling height, with a broomlike array of many five-angled flexible branches. Leaves appear mainly on lower branches, each made up of three leaflets. Some leaves grow on the upper branches; these are generally made up of a single leaflet. Each leaflet is under a centimeter long and may be linear to oblong in shape and coated in soft silvery hairs. The white, pea-like flower is up to a centimeter long and is often marked with a dark pinkish streak near the base. The fruit is a hairy legume pod up to {{convert|3|cm}} long. The pods turn black with age and dehisce explosively to release their four to six seeds away from the parent plant. Invasive speciesThis plant is a serious noxious weed of agricultural fields and a colonizing invasive plant in wild lands in parts of Australia and California,[4] where it was first introduced as an ornamental shrub for its prolific white flowers. It is still sometimes grown and sold for landscaping purposes despite its status as a pest plant, with new industry and public education programs resulting.[5][6] References1. ^{{cite web|url=http://www.theplantlist.org/tpl1.1/record/ild-8771|title=The Plant List: A Working List of All Plant Species|accessdate=3 April 2014}} 2. ^{{cite web|title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |archive-url=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archive-date=25 January 2015 |accessdate=17 October 2014 |deadurl=yes |df= }} 3. ^{{PLANTS|id=CYMU3|taxon=Cytisus multiflorues|accessdate=17 January 2016}} 4. ^Jepson 5. ^{{cite web |url=http://www.weeds.gov.au/publications/guidelines/alert/pubs/c-multiflorus.pdf|title=Weeds in Australia|publisher=Australian Weed Management|format=PDF|accessdate=24 November 2010}} 6. ^{{cite web|url=http://www.dfg.ca.gov/invasives/ |title=What are invasive species and why are they a problem?|publisher=Calif.
