Plum, Purpleleaf or Cherry or Myrobalan
Prunus cerasifera
Rosaceae - Rose

Description

Leaves: Alternate; simple; ovate to obovate; 1-1/2" to 2-1/2" long and half as wide; deciduous; usually purple-green to dark purple, occasionally dark green; glabrous above and beneath except for hairs along veins beneath; finely serrate margin; may have glands where petiole attaches to blade.

Twigs/buds: Twigs slender; glabrous; silver-gray when young, dark gray when older. Buds 1/4" long, scaly, dark purple-gray.

Flowers/fruit: Flowers perfect, pink or white, 3/4" to 1" in diameter; appearing in early spring. Fruit a one-seeded round drupe (plum) about 1" in diameter; dark purple; usually present in small numbers; sweet and edible; maturing in mid-summer.

Bark: Shiny smooth and dark purple at first with small horizontal lenticels, roughening with age with small vertical cracks and enlarging brown lenticels.

Wood: Not important and essentially unknown; dark heartwood.

General: Native to western Asia and cultivated for centuries. Fairly adaptable to different sites, but also pest-prone like many Rosaceae. Shade intolerant. Weak wood and/or branch structure. Fruit and/or plant part can be nuisances; use fruitless varieties if possible.

Landscape Use: A small tree widely used in the landscape, in Utah mostly as the purple-leaved cultivar 'Newport'. I have had two of these trees in my yard in Logan and was not impressed. Included bark and weak branch attachments are common. Reputed to lack cold-hardiness, but mine survived the cold, only to succumb to branch breakage and trunk decay. However, it is beautiful in bloom. Zones 5(4?)-8.

Cultivars: 'Alfred', 'Atropurpurea', 'Clark Hill Redleaf', 'Festeri', 'Hessei', 'Hollywood', 'Krauter Vesuvius', 'Mt. St. Helens', 'Newport', 'Nigra', 'Purple Pony', 'Purpusii', 'Thundercloud', 'Vesuvius'.
