Forsythia x intermedia
Deciduous, Ground covers, Shrubs
Native to China and Korea. From late winter to early spring, these fountain-shaped shrubs’ bare branches are covered with 3/4–1 1/2-in. yellow flowers; budded branches can be forced for indoor bloom. During the rest of the growing season, medium green, rounded leaves with pointed tips blend well with other background shrubs. Use as a screen, espalier, or bank cover; or plant in a shrub border. Tolerate most soils. Prune after bloom by cutting to the ground a third of the branches that have flowered; also remove the oldest branches and weak or dead wood. In coldest-winter climates, flower buds may be destroyed by temperatures of 15° to 20°F/26° to 29°C.
