Shrubs, saplings or small trees, deciduous, native to Asia and very popular in Japan where, together with the flowering Cherry and Pine they are the main attraction in all parks and gardens. They have a very harmonious form, elegant leaves that create attractive, colourful symphonies that change according to the season. In spring, small, reddish-purple flowers with yellow stamens grouped in hanging clusters appear. Very attractive, bright red, winged fruits, brown when mature, follow. They grow quite rapidly when young, and then more slowly, withstand the cold but may be damaged by late frosts, especially when young. They require cool, light, moist but well drained soil, slightly acid and clay. Good results are obtained in different types of soil as long as it is not heavy, stagnant or calcareous and an acidic supplement is given. Must be placed in half-shade or in a sunny position, protected from strong winds. Half-shade is absolutely necessary if the soil is sandy or very light, in hot or dry areas.
