Overview

Pinus sylvestris is an upright coniferous evergreen tree growing 40-60 feet (12-18 m) tall and 20-35 feet (6-10.7 m) wide. Blue-green to gray-green stiff twisted needles are borne in fascicles of 2, 1.5-3 inches (4-7 cm). The specific epithet sylvestris means of the forest. The species has a wider natural range than any other pine, extending from Scotland east across Eurasia to the Sea of Okhotsk at elevations from sea level to 7,900 feet (2,400 m). P. sylvestris is a 2-needle pine in subgenus Pinus. Orange-red to salmon flaking bark on the upper trunk and branches is the primary identification feature and becomes most visible in winter against bare-branched companion species. Diplodia tip blight is the primary disease in North America. Pine wilt nematode is fatal and increasingly common in the central and eastern United States — infected trees cannot be saved and are removed promptly to limit spread. The species is intolerant of hot humid climates and does not perform well in the southeastern United States; this humidity intolerance is the primary climatic limitation. Tolerates extreme cold (USDA zone 2), drought, wind, and poor soil. Non-toxic. Deer-resistant.

Native Range

Native from Scotland east across Eurasia to the Sea of Okhotsk. Found from sea level to 7,900 feet (2,400 m). The species has a wider natural range than any other pine.

Suggested Uses

Grown as a specimen tree, windbreak, or screen in cool dry climates on sites with room for 40-60 foot (12-18 m) height and 20-35 foot (6-10.7 m) spread, spaced 20-35 feet (6-10.7 m) apart. Not suited for hot humid regions. The orange-red upper bark gives year-round visual interest. Mature size exceeds typical container dimensions. Non-toxic. Hardy in zones 2-8.

How to Identify

P. sylvestris is identified by orange-red to salmon flaking bark on the upper trunk and branches, short stiff twisted needles in fascicles of 2 (1.5-3 inches / 4-7 cm), and gray-brown ovoid cones 1.5-3 inches (4-7 cm). The orange-red upper bark is the primary diagnostic. Separated from P. mugo (shrubby habit, no orange bark) and P. nigra (longer stiffer needles, dark bark throughout).

Care & Maintenance

Care Guide

Site in full sun (6-12 hours) in well-drained soil with a pH of 4.5-7.0. Drought-tolerant. Not suited for hot humid regions; the species declines in the southeastern United States. Diplodia tip blight is the primary disease; affected shoots are pruned out in dry weather with tools disinfected between cuts. Pine wilt nematode is fatal — infected trees are removed promptly. No pruning is needed on healthy trees. Non-toxic. Deer-resistant. Hardy in zones 2-8.

Pruning

No pruning is needed. The natural form develops without intervention. Remove dead or damaged branches. If Diplodia tip blight is present, prune affected shoots in dry weather and disinfect tools between cuts.
