Spiraea, Philadelphus and Weigela, could be considered to be the holy trinity of summer flowering shrubs, these are the back bone and structure to any good large boarder planting scheme. Often summer colour is thought of as roses and herbaceous planting and shrubs get over looked. But they have much to add when in and out of flower and no good planting scheme would be with out these three. Here are some varieties to consider.
Philadelphus ‘Belle Etoile’: ‘mock orange’, it is all about the scent with Philadelphus, and this variety has to be amongst the best. A medium sized shrub with tall upright, arching growth, gives a statuesque feel to the boarder. Mid green leaves and wide open white flowers flushed with a maroon centre. Flowering June to July. Sun part shade.
Phiadelphus ‘Manteau d’ Hermine’: A compact variety producing a neat mound of low growth with fresh green leaves. Long lasting sweetly scented flowers June into July. Will grow in any reasonable soil with good drainage, they do not like being water logged.
Spiraea aruguta: ‘ Bridal wreath’, this is a truly spectacular late spring early summer shrub, when in full flower. A mound forming medium sized shrub with long arching branches, it really must be given it’s head and allowed to fully develop its habit, which is graceful and eye stopping, but sadly to often is hacked into submission. Small clusters of white flowers produced in profusion line the branches from April to May. Followed by small mid-green leaves. Sun or a little shade.
Spirea japonica ‘Candle Light’: This is a small compact growing Spiraea ideal for the small garden or flower bed. With a compact dense habit and small bushy soft yellow leaves that mature into a strong yellow. Flat heads of soft pink flowers are produced from July to August. Sun or a little shade. These tough shrubs will put up with a lot of different soil conditions but not water logging.
Weigela florida ‘Foliis Purpureis’: A small to medium shrub which is slow growing with a dense compact habit. With grey-purplish leaves which act as a stunning foil for the pink trumpet like flowers produced in clusters from May to June. Grow in full sun although will tolerate a little shade. All good well drained soils.
Weigela flordia varigata: Medium sized shrub with a dense habit. Leaves have a delicate variegation of creamy white edging to the leaves. Scented pink flowers in June. Best grown in dappled shade, so the variegated leaves do not get scorched.
Tips: These three hardy shrubs will grow nearly anywhere. From good rich soil to thin chalk. They like good light levels and a sunny spot, but the yellow leaved and variegated forms of all three shrubs are prone to scorching in very hot sunny potions. Only prune if really needed, to reduce size or remove very old or diseases wood. If you have chosen the right shrub for the space it should not need to be pruned. If you do need to prune, then after flowering is the best time, to allow for regrowth and the development of next years flowers.
I hope I have inspired you to take a fresh look at these under used shrubs, with their long flowering season, scent, spectacular flower displays and varied foliage colour. As well as the range of sizes. These shrubs really do deserve to be planted much more widely.
