The genus includes about seven to eleven species, most native to eastern Asia with one from southeastern Europe. In Canada, forsythia is widely grown as a hardy ornamental shrub and is commonly one of the first shrubs to bloom in spring.

Taxonomy and naming

Forsythia belongs to the family Oleaceae. The genus was named for William Forsyth, a Scottish botanist and horticulturist associated with the Royal Garden at Kensington and the Royal Horticultural Society.

Distribution and native range

Most forsythia species are native to eastern Asia, while one species is native to southeastern Europe. Some species and hybrids have become widely planted beyond their native range.

Cultivation and landscape use
