'''''Forsythia''''' ({{pron-en|fɔrˈsɪθiə}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a genus of [[flowering plant]]s in the family [[Oleaceae]] (olive family). There are about 11 species, mostly native to eastern [[Asia]], but one native to southeastern [[Europe]]. The common name is also '''Forsythia'''; the genus is named after [[William Forsyth (botanist)|William Forsyth]].<ref name=foc>Flora of China: [http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=112951 ''Forsythia'']</ref><ref name=fe>Flora Europaea: [http://rbg-web2.rbge.org.uk/cgi-bin/nph-readbtree.pl/feout?FAMILY_XREF=&GENUS_XREF=Forsythia&SPECIES_XREF=&TAXON_NAME_XREF=&RANK= ''Forsythia'']</ref><ref name=stabg>St Andrews Botanic Garden: [http://www.st-andrews.ac.uk/~gdk/stabotanic/aprilpom.htm Plant of the Month: ''Forsythia'']</ref>

They are [[deciduous]] [[shrub]]s typically growing to a height of {{nowrap|1&ndash;3 m}} {{nowrap|(3&ndash;9 ft.)}} and, rarely, up to {{nowrap|6 m (18 ft.),}} with rough grey-brown [[bark]]. The [[leaf|leaves]] are opposite, usually simple but sometimes trifoliate with a basal pair of small leaflets, and range from {{nowrap|2&ndash;10 cm (1&ndash;4 in.)}} in length and, rarely, up to {{nowrap|15 cm (6 in.)}} long; the margin is serrated or entire. The [[flower]]s are produced in the early spring before the leaves, bright yellow with a deeply four-lobed [[Corolla (flower)|corolla]], the petals joined only at the base. These become pendant in rainy weather thus shielding the reproductive parts. The Forsythia's flowers are impressive with the fact that they are able to produce [[lactose]] (the [[milk]] sugar). Lactose is very rarely established in other natural sources except [[milk]]. The actual [[fruit]] is a dry capsule, containing several winged [[seed]]s.<ref name=foc/><ref name=rhs>Huxley, A., ed.

Forsythia (after William Forsyth, prominent English horticulturist, director of the Royal Garden at Kensington, 1737-1804). Oleaceae. Golden- Bell. Shrubs grown for their wealth of bright yellow flowers appearing early in spring, also for their handsome dark green foliage.
