Prunus or Ornamental Plum belongs to the Rosaceae family. This huge genus comprises a large number of trees and shrubs with decorative foliage or blossom, so its diversity has something to offer for gardens of all sizes. In addition, the genus includes Apricots, Cherries, Laurel (Prunus lauroceasus), Wild Cherry and Ornamental Peach. There are broadly speaking 3 groups of Prunus: those with blossom, those with deciduous leaves, and those with evergreen foliage where the blossom is more or less a feature.
