Hedges are a valuable, versatile plant in the home landscape, providing a barrier, privacy screen, or windbreak. A flowering hedge will serve all of these purposes, and provide beauty, as well. While some flowering hedges can take years to reach their full, mature size, others are speedy growers that will fulfill their intended purpose very rapidly.
Flowering quince (Chaenomeles speciosa) is a drought-tolerant, deciduous shrub thats grow in nearly any well-drained soil. Depending on the variety, the flowers are available in white, apricot and bright red and appear in spring, resulting in a showy flowering hedge. Flowering quince is hardy to U.S.Department of Agriculture climate zones 4 to 8.
With showy clusters of flowers in shades of purple, pink, white and lavender that appear in late spring, common lilac (Euonymus alatus) reaches its mature size of 8 to 15 feet quickly. Common lilac does best in full sunlight and once established will grow for many years with virtually no maintenance. Common lilac works well as a hedge, border or screen and is hardy in USDA Zones 3 through 7.
Prague viburnum (Viburnum x pragense) is a plant for the impatient gardener, producing a sturdy, evergreen hedge in a short time. Prague viburnum is an early bloomer with pink buds that appear in spring, soon to followed by clusters of creamy white flowers with a pleasant, spicy aroma. Prague viburnum thrives in full sunlight to partial shade, and is hardy in USDA zones 5 through 8.
Japanese spirea (Spiraea japonica) produces clusters of bright pink blooms in early summer. A fast-growing shrub with a pleasant, rounded shape, Japanese spirea is relatively drought-tolerant, but prefers well-drained, moist soil and full sunlight. The foliage is nearly as colorful as the blooms, ranging in hue from bluish green red, bronze, orange of burgundy, depending on the season. Japanese spirea is hardy in USDA zones 4 through 8.
