Hedges not only add privacy to your garden, but they also improve its aesthetics. Hedges are often thought to be evergreen shrubs or trees, but some large, fast-growing flowering shrubs make colourful hedges, offering a variety of foliage, texture and blooms. The best hedges are those with a dense and compact growth habit. If you want year-round privacy, choose flowering plants with evergreen foliage.
Showy border forsythia
Showy border forsythia, Forsythia x intermedia, is a fast-growing shrub with a mature size of around 3 metres (10 feet) tall and 3.6 metres (12 feet) wide. Its upright growth habit and long-lived nature make it ideal for a hedge offering seasonal privacy. In early spring, border forsythia produces bell-shaped yellow flowers that are around 3.75 cm (1 1/2 inches) long, followed by dark-green foliage that lasts into autumn. Plant the shrub in full sun. It prefers fertile, well-drained soil, but adapts to a variety of soil types. Prune border forsythia to keep it in shape as a hedge.
Cherry laurel, Prunus caroliniana, is a fast-growing evergreen shrub reaching 6 metres (20 feet) tall or more and is commonly used as a low-maintenance hedge. Its glossy leaves are 5 to 10 cm (2 to 4 inches) long and range in colour from yellow-green to dark green. Cherry laurel produces 7.5 cm (3 inch) long flower clusters in late winter and early spring, followed by 1.25 cm (1/2 inch) blue-black fruit. Cherry laurel thrives in areas of sun but is moderately tolerant to shade. Established plants are drought tolerant.
