Forsythia is a genus of deciduous flowering shrubs in the olive family (Oleaceae), known for its bright yellow flowers that often appear before the leaves in early spring. 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.
Description
Forsythia shrubs are deciduous and typically have opposite leaves, arching stems, and yellow flowers with four petals. The flowers often appear in early spring before the leaves, and the fruit is usually a capsule.
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
Forsythia is commonly grown as an ornamental shrub because it is fast-growing and easy to maintain. It is often used in hedges, borders, screens, and other landscape plantings.
