Plant Species of the genus Prunus

Information about this genus
Name: Prunus
Cultivation: CULTIVATION: Although hardiness varies with the species, most need some winter chilling to flower and fruit properly. Wind protection is important to gain the most benefit from the flowers, either ornamentally or for setting fruit. Some species prefer long cool summers, but most need summer heat to ripen their fruit. Most species are not overly fussy about soil type, though few are drought tolerant and most prefer cool, moist, well-drained soil that is both fertile and humus rich. Correct pruning techniques are important for the fruiting varieties, less so for the ornamentals. If silverleaf disease is present do not prune in winter, instead cutting back in summer or immediately after harvest. Propagate the species from seed, the fruiting forms by grafting and the ornamentals by grafts or in some cases by cuttings. Special forms such as weeping standards require 2 or more grafts.
Description: Including both ornamental and fruiting species, many of great commercial significance, this widely grown genus is naturally widespread throughout the northern temperate regions and also has a toehold in South America. Best known for the edible stone fruits (cherries, plums, apricots, peaches and nectarines) and their ornamental flowering cousins, the genus includes a wide range of shrubs and trees, mostly deciduous, ranging from 3?ft (1?m) to over 80?ft (24?m) tall. Most bloom from late winter to early summer, producing 5-petalled flowers either singly or in clusters, in colors from white through to dark pink, followed by fleshy single-seeded fruit. The leaves are usually simple pointed ellipses, often with serrated edges, and sometimes develop brilliant autumn colors. This large and variable genus is divided into several subgenera, based mainly on their flowering and fruiting characteristics.
