PINUS cembra 'Compacta Glauca'

Family

Pinaceae

Botanical Name

PINUS cembra 'Compacta Glauca'

Plant Common Name

Swiss Stone Pine

General Description

A slow-growing tree from mountains of Europe and western Asia, Swiss stone pine is prized for its compact, symmetrical, upright form. The cultivar 'Compacta Glauca' has blue-green needles and a narrow, semi-dwarf habit.

The long, stiff, blue-green needles of this evergreen conifer occur in bundles of five. In spring, trees produce tiny male cones and larger female cones near the branch tips. Female cones persist 3 years, maturing to purple-blue and then brown. Mature female cones are the size and shape of a large egg, and do not open.

A conical to pyramidal shrub or small tree, 'Compacta Glauca' typically retains its lower limbs and its dense narrow habit for many years, but may become broader and more open in old age.

This tough, adaptable, and beautiful pine favors full sun and well-drained, humus-rich soil. It does poorly in hot arid climates. With its dense, upright, somewhat formal bearing, it is perfect as an accent or for grouping in residential and public landscapes.
