Morphology and biology.

Plant is a shrub up to 1 (1.5) m tall, with light-gray or sometimes brown branches. Young shoots are reddish-brown, often glaucous, thin. Buds have broad obtuse scales; inner ones are glandular along the edge. Leaves are 3-7 cm long and 1.7-3 cm wide, varying in shape from ovate to oblong and lanceolate, gradually or abruptly tapered into a long sharp point, finely dentate along the edge, sometimes doubly adenodentate, naked or covered with sparse hairs from above and pilose only along the main vein from below. Petioles are 2-7 mm long, without glandules. Flowers are solitary or grouped in umbels of 2 or 3, set on naked or slightly adenotrichous pedicels that are 1-2 cm long. Flowers open simultaneously with leaves or a little earlier. When plant begins to blossom, blossoms are red, but later turn pink or less frequently white, reaching 1.5-2 cm in diameter. Hypanthium is broadly bell-shaped. Sepals are 3-5 mm long, adenodentate, deflected. Fruits are 1 (1.2) cm in diameter, dark-red, globular, edible. Stones vary from almost spherical to obovoid, acuminate, with faintly expressed striation. Entomophilous. Ornito- and zoochore. Plant is propagated by seed and summer cuttings. Seed require stratification for 4-5 months at 1-5 degrees Centigrade. Blossoms in May, bears fruit in August. 2n=16.

Distribution.

Grows throughout the Russian Far East (south of Maritime Region); China, Korea and Japan.

Ecology.

Mesophyte. Photophilous. Plant is drought-resistant. It grows as solitary plants or in small groups on dry stony mountainsides among shrubby thickets and in river valleys on dry and non-flooded sites.

Utilization and economic value.

Plant is used as food (fruit), ornamental and as a nectariferous species. This species is close to the Chinese cherry (Cerasus japonica (Thunb.) Loisel.) and has been cultivated in Japan since early times. Used for breeding new dwarf and frost-resistance varieties. Among cultivated forms there is a very ornamental one with double pink flowers.
