Spiraea Salicifolia

The willow spiraea is native to southern Europe, its range extending to central Europe and eastward as far as eastern Asia and Japan. Even though very hardy, it is not often seen in parks and gardens. It is a 1.5 to 2m (5 to 6 ft) high shrub of stiff, upright habit, with salmon-pink flowers borne in dense, 10 to 12cm (4 to 5in) long pyramidal panicles which appear in June and July. It is a good subject for group plantings and for filling in odd spaces. In parks and gardens it is effective planted with dark green conifers’ such as yews, early-flowering quinces or forsythias, or fronted by low perennials.

Spiraeas are generally propagated by softwood summer cuttings or hardwood winter cuttings, as the seeds do not germinate reliably. These are inserted in a frame into a mixture of sand and leafmould and transferred to pots when they have put out roots. In the second year they can be planted out in their permanent site. Some species produce a great many suckers and can be increased by this means as well. Dense shrubs can be propagated by division. Spiraeas stand up well to pruning but this modifies flowering. Early-flowering spiraeas should be pruned immediately after flowering, late-flowering species in winter.
