Forsythia x intermedia (Border Forsythia)
Border Forsythia, Common Forsythia
Forsythia x intermedia (Border Forsythia) is a deciduous shrub forming a graceful fountain with its upright-arching to spreading branches bending to the ground. They are clad with ovate, sharply serrated, medium to dark green leaves, up to 5 in. long (12 cm), which die off green or with a hint of burgundy in the fall. In early to mid-spring, a profusion of brilliant yellow, four-petaled flowers open on the naked branches. The flower effect is spectacular, brightening the landscape at a time when not much else is in bloom. Border Forsythia is extremely adaptable, tolerating most soils and climates. Great in mass plantings, shrub borders, or as a flowering hedge.
- Grows up to 8-10 ft. tall (240-300 cm) and 10-12 ft. wide (300-360 cm).
- A full sun or part shade lover, this plant is best grown in moist, well-drained soils. Best flower production is obtained in full sun. Tolerates average to poor garden soils. Some drought tolerance once established.
- Perfect as a specimen plant, for foundations or hedges, in mixed borders, on banks or slopes. Great for coastal gardens, or cottage gardens.
- Low maintenance, this plant is deer resistant and fairly trouble-free. Keep an eye out for leaf spots, crown gall, spider mites, and aphids.
- Prune immediately after spring flowering to encourage strong, healthy shoots and improve flowering.
- Propagate by semi-hardwood cuttings
