Flowering shrubs can add color and fragrance to a garden hedge and be a great addition to the garden. They can create garden rooms, screen out an unattractive view, or act as a barrier to keep out animals or unwanted visitors. There are many different flowering shrubs that make good hedges so there is probably one that will meet the wants and needs of every gardener.
The five shrubs described below respond to pruning well and can be trained into a hedge.
Late Lilac (Syringa villosa)Late lilac has a lot to offer. It is one of the hardiest of the lilacs, its flowers open a full week after the flowers of common lilac have faded, and it’s dense growth and shorter stature makes it a fine candidate for a hedge. The flowers are rosey-lilac to white. True, they are not as fragrant as those of common lilac but the overall appearance of the shrub makes it a good choice for a hedge.
Bloom Time: Spring, a full week after common lilac
Light : Full sun
Soil: Average, moist, well-drained
Hardiness: Zones 3-7.
Bridlewreath (Spirea x vanhouttei)The graceful branches covered with white flowers and the arching habit make this a prized shrub in spring. Add to that its vigorous growth and dependability and you have an outstanding shrub, one of the best spireas available.
Bloom Time: Mid spring
Light: Average, medium moisture, well-drained
Soil: Full sun
Hardiness: Zones 3-8.
Flowering Quince (Chaenomeles speciosa)The white, pink, or red flowers may be single or double and are borne before the leaves on twiggy branches.
