Care of the shrub Spiraea japonica or Japanese spiraea |
|
The genus Spiraea, family Rosaceae, comprises 100 species of shrubs native to Asia. Some species are: Spiraea japonica, Spiraea cantoniensis, Spiraea prunifolia, Spiraea salicifolia, Spiraea alba, Spiraea splendens, Spiraea x vanhouttei (hybrid). Common names: Reeve's spiraea, Bridalwreath spirea, Double White May, Cape May. This species is native to China and Japan. They are semi-perennial shrubs that reach 1.5 meters (4.92 feet) in height. The leaves are deep green in color, with a serrated edge and a lanceolate shape ending in a point. The abundant flowers appear in terminal corymbs and are usually pink, although there are varieties of fuchsia pink, red or white. They bloom in summer. They are used in rockery, in bushy groups, on borders, on slopes and in pots for patios and terraces. They resist pollution from cities well. Spiraea japonica prefers a semi-shady exposure and a temperate climate. They resist occasional frosts. The soil can be a light garden soil with plenty of manure or compost. Transplantation or planting is done in spring or fall. Water regularly so that the substrate always remains moist and fresh but without waterlogging. Fertilize with manure in late winter and with mineral fertilizer every 20 days in spring and early summer. Prune lightly after flowering to maintain a compact appearance. They are quite resistant plants to the usual pests and diseases. They are propagated in spring by cuttings or from the suckers that the plant itself produces at the base. |
