Spectabilis Forsythia is one of several popular varieties of Forsythia x Intermedia and is also known by the scientific name Forsythia x Intermedia 'Spectabilis'.
This variety is a medium-sized, deciduous, multi-stemmed forsythia bush that is growing upright and spreading.
It grows from 2.1 to 2.8 metres (7 to 9 feet) in height and spreads about 1.8 to 2.5 metres (6 to 8 feet). This forsythia variation is a fast growing and long-lived plant that grows about 0.4 metres (about 1.3 inches) per year.
It can be planted solitary or in groups and is an excellent hedge plant that can also get trimmed back without any problems. It is also an excellent plant to control erosion and is therefore often planted on steep slopes. It transplants and spreads easily and makes an excellent border plant as well.
This is an easy to care for forsythia plant, like most other (almost all) forsythia. It tolerates any ordinary garden soil and grows preferably in full sun (yet, partial shade is also tolerated). Keep it well-drained, but avoid overwatering it.
This showy forsythia shrub has especially vibrant, golden, bell-shaped and large flowers in great abundance! It blooms all along the branches in early spring from March to April ahead of the foliage. Do not forget to prune it after flowering. This will promote again the abundant growth of flowers the coming year!
The foliage has an attractive forest green colour throughout the growing season. Yet, there is no significant fall colour.
Tip: This forsythia bush is great for cuttings! Cut the branches before flowering in late winter and put them in a vase with fresh, warm water. Then, simply enjoy the vibrant gold flowers in your home!
Tip: Forsythias, unfortunately, do not provide any food for insects. It is wise to also plant some native plants that attract butterflies, flies, bees, bugs and also birds and other wildlife!
