Forsythia

Forsythia — Forsythia is a genus of flowering plants 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.

They are deciduous shrubs growing to 1–3 m (rarely 6 m) tall, with rough grey-brown bark. The leaves are opposite, usually simple but sometimes trifoliate with a basal pair of small leaflets, and range from 2–10 cm (rarely to 15 cm) long; the margin is serrated or entire. The flowers are produced in the early spring before the leaves, bright yellow with a deeply four-lobed corolla, the petals joined only at the base. The fruit is a dry capsule, containing several winged seeds.

Forsythias are popular early spring flowering shrubs in gardens and parks. Two are commonly cultivated for ornament, Forsythia × intermedia and Forsythia suspensa. They are both spring flowering shrubs, with yellow flowers. They are grown and prized for being tough, reliable garden plants. Forsythia × intermedia is the more commonly grown, is smaller, has an upright habit, and produces strongly coloured flowers. Forsythia suspensa is a large to very large shrub, can be grown as a weeping shrub on banks, and has paler flowers. Many named garden cultivars can also be found.
