Spiraea cantoniensis

Spiraea contains some 80 species of deciduous and semi-evergreen shrubs grown primarily for their spring or summer floral display. They form clumps of wiry arching stems clothed in narrow toothed leaves. They are hardy and versatile, but do best in fertile, well drained soil, and in hotter climates, in a position out of the full afternoon sun. They are both frost and drought tolerant once established. Single Flowering May is a must-have for the spring garden. It's flowers smother the branches and last for many weeks. It is a good choice for an informal hedge in a country-style garden. After several years, it can be pruned to the ground to refresh the plant.
