"Notes: Western Ghats, Cultivated, Native of East Asiatic Region"
Japanese spiraea, also called Japanese meadowsweet, is a perennial, deciduous shrub that grows to 4 or sometimes 6 feet in height and about the same in width. It has slender erect stems that are brown to reddish-brown, round in cross-section and sometimes hairy. The leaves are generally egg-shaped, 1-3 inches long, have toothed margins and alternate along the stem. Clusters of attractive, rosy-pink flowers are borne at the tips of branches. Seeds, measuring about 1/10 inch in length, are contained in small lustrous capsules. Japanese spiraea is naturally variable in form and there are many varieties of it in the horticultural trade.
