Prunus is a large genus of over 400 species and hybrids in the rose family which includes apricots, nectarines, peaches, cherries, plums and almonds. Stone fruit trees are important agricultural crops, but many are also grown for their ornamental value. Flowering cherries are prized for their showy spring blooms, fall foliage and attractive bark. The historic Tidal Basin cherry trees in Washington, DC are perhaps the most famous display of this popular landscape plant in the US. Flowering plums, particularly purple-leaved cultivars, are also widely grown. Like other members of the rose family, Prunus has many potential disease and insect problems and some types may be short-lived in the landscape.
