There are several species of flowering or ornamental Plums (as distinct from the fruit-bearing kinds), and a good trade is done in them. The Cherry or Myrobalan Plum (P. cerasifera), from the Caucasus, produces its white flowers in April, and is largely used for hedge purposes. The purple-leaved variety, atropurpurea (or Pissardi), is extensively grown, and sprays of foliage are largely used for decorative purposes by florists, etc. The Blackthorn or Sloe (P. spinosa) of the hedges has yielded a purple-leaved form and also one with beautiful double flowers. The finest-flowering Plum, however, is the double-flowered P. triloba, from China, which produces its masses of rose-tinted white flowers in great profusion at the end of March and early in April. The single-flowered type (fig. 431), with rose-white flowers, has been introduced of late years. The Plums flourish in good loamy soil, and are usually budded or grafted on common Plum stocks or layered. (See also "Cerasus", "Amygdalus").
