description_en: Genus of about 80 species of deciduous or semi-evergreen shrubs found in rocky places, thickets, woodland, at woodland margins, and on riverbanks, widely distributed in N. temperate regions of Europe, Asia, and North America, including Mexico. The alternate leaves are entire, toothed, or lobed, and are decorative in some species. Spiraeas are cultivated mainly for their terminal, umbel-like racemes, panicles, cymes, or corymbs of small, mostly saucer-, cup-, or bowl-shaped, white, yellow, pink, or purple flowers; these are 0.5-1cm (1/4-1/2in) across, or sometimes slightly larger, and profusely borne in spring or summer. Grow in a mixed or shrub border. Compact spiraeas are ideal for a rock garden; use low-growing variants of S. japonica as ground cover; use taller spiraeas as informal hedging.

hardiness_en: Fully hardy, although new growth on early-flowering species and cultivars may be damaged by late frosts.
