Worldwide, there are now about 1800 botanical gardens and [[arboretum|arboreta]] in about 150 countries (mostly in temperate regions) of which about 550 are in [[Europe]] (150 of which are in [[Russia]]),<ref>{{cite journal |last=Gratani |first=Loretta |date=15 January 2008 |title=Growth pattern and photosynthetic activity of different bamboo species growing in the Botanical Garden of Rome |url=https://www.sciencedirect.com/science/article/abs/pii/S0367253007001247 |journal=Flora - Morphology, Distribution, Functional Ecology of Plants |volume=203 |issue=1 |pages=77–84 |doi=10.1016/j.flora.2007.11.002 |bibcode=2008FMDFE.203...77G |via=Science Direct}}</ref> 200 in [[North America]],<ref name=bhist /> and an increasing number in East Asia.<ref>{{cite web |url=http://202.127.158.171/eabgn/english/index.htm |title=东亚植物园 |publisher=East Asia Botanic Gardens Network |access-date=8 November 2011 |url-status=dead |archive-url=https://web.archive.org/web/20080123222721/http://202.127.158.171/eabgn/english/index.htm |archive-date=23 January 2008}}</ref> These gardens attract about 300 million visitors a year.<ref>{{Cite journal |last1=Williams |first1=Sophie J. |last2=Jones |first2=Julia P.

Historically, botanical gardens exchanged plants through the publication of seed lists (called {{langx|la|Indices Seminae}} in the 18th century). This was a means of transferring both plants and information between botanical gardens. This system continues today, though with attention to the risks of genetic piracy and transmission of [[invasive species]].<ref name=h11>{{Harvnb|Heywood|1987|p=11}}</ref>

The International Association of Botanic Gardens<ref>{{cite web |url=http://www.bgci.org/index.php?option=com_content&id=1530 |title=International Association of Botanic Gardens (IABG) |work=BGCI.org |publisher=Botanic Gardens Conservation International |access-date=8 November 2011}}</ref> was formed in 1954 as a worldwide organisation affiliated to the [[International Union of Biological Sciences]]. More recently, coordination has also been provided by [[Botanic Gardens Conservation International]] (BGCI), which has the mission "To mobilise botanic gardens and engage partners in securing plant diversity for the well-being of people and the planet".<ref>{{cite web |url=http://www.bgci.org/global/mission/ |title=Mission statement |work=BGCI.org |publisher=Botanic Gardens Conservation International |access-date=8 November 2011 |archive-url=https://web.archive.org/web/20111028054037/http://www.bgci.org/global/mission |archive-date=28 October 2011 |url-status=dead}}</ref> 

Regional co-ordination is seen in the United States with the [[American Public Gardens Association]]<ref>{{cite web |url=http://www.publicgardens.org/ |title=American Public Gardens Association |work=publicgardens.org |publisher=American Public Gardens Association |access-date=8 November 2011}}</ref> (formerly the American Association of Botanic Gardens and Arboreta), while in Australasia there is the Botanic Gardens of Australia and New Zealand (BGANZ).<ref>{{cite web |url=http://www.bganz.org.au/ |title=Welcome to BGANZ |year=2011 |work=BGANZ.org.au |publisher=Botanic Gardens Australia and New Zealand Inc |access-date=8 November 2011}}</ref>
