== Cultivation ==

A number of Saxifragales genera are commercially cultivated.{{sfn|Christenhusz et al|2017}} ''Paeonia'' are cultivated both as ornamental shrubs (generally sold as [[root stock]]) and for [[cut flowers]], with the Netherlands representing the largest production, other more minor producers are Israel, New Zealand, Chile and the United States.{{sfn|Auer|Greenberg|2009}} ''Liquidambar'' is used for hardwood, with the American Sweetgum (''Liquidambar styraciflua'') being among the most important sources of commercial [[hardwood]] in the Southeast United States, with one of its uses being [[Veneer (wood)|veneer]] for [[plywood]].{{sfn|Kormanik|1990}} ''Hamamelis'' is cultivated in New England for distilleries extracting witch-hazel, widely used in skincare, and is the largest source of this medicament in the world.{{sfn|Gapinski|2014}} Among the Crassulaceae, economic importance is limited to [[horticulture]], with many species and cultivars important as ornamentals, including ''[[Crassula ovata]]'' (jade plant) and ''Jovibarba'' (hen and chicken). ''Hylotelphium'', ''Phedimus'', ''Sedum'' and ''Sempervivum'' are cultivated for [[rock gardens]] and for "[[green roofs]]".{{sfn|Earle|Lundin|2012}}{{sfn|Thiede|Eggli|2007}} In particular, cultivars of the Madagascan ''[[Kalanchoe blossfeldiana]]'', e.g. 'Florists kalanchoe' have achieved commercial success throughout the world, being popular Christmas decorative plants.{{sfn|Smith et al|2019}}{{sfn|Gwaltney-Brant|2012}} The Haloragaceae aquatic genus ''Myriophyllum'' and the closely related ''Proserpinaca'' are cultivated for the commercial [[aquarium]] trade.{{sfn|Goldstein et al|2000}} ''Myriophyllum'' is also economically important for purification of water and as feed for pigs, ducks, and fish, and polishing wood.{{sfn|Chen|Funston|2004}}

A number of ''Ribes'' (Grossulariaceae) are in commercial production, concentrated in Europe and the USSR from species native to those areas. ''[[Ribes nigrum|R. nigrum]]'' (blackcurrant) was first cultivated in [[monastic garden|monastery gardens]] in Russia in the 11th century, and currant cultivation more generally later in Western Europe, ''[[Ribes uva-crispa|R. uva-crispa]]'' (gooseberry)  production began around 1700. The first colonists in North America began cultivating currants in the late 1700s. ''R. nigrum'' is the most important commercial currant crop, being produced in more than 23 countries, with the major centres being Russia (more than 63 thousand [[hectares]]), Poland, Germany, Scandinavia and the UK.{{sfn|Brennan|2008b}} An important source of [[Vitamin C]], black currants are used in the manufacture of jam, fruit jelly, compote, syrup, juice and other drinks, including the [[Cordial (drink)|cordial]] [[Ribena]] and the [[liqueur]] [[Crème de cassis|Cassis]]. Other commercial crops include ''[[Ribes rubrum|R. rubrum]]'' (red currant).{{sfn|Doronina |Terekhina|2009}}{{sfn|Gros d'Aillon|2016}} World ''Ribes'' crop production was over 750,000 tons in 2002, of which about 150,000 tons were gooseberries, and the largest group blackcurrants.{{sfn|Brennan|2008a}}
