Summary

Tree

Pinus nigra is a tree that can reach 75-80 feet in height at maturity and has an overall pyramidal form.

Bark

Its bark is gray, becoming rough and fissured with age.

Twig

Twigs are stiff, brown-hued, and become darker with time.

Leaves

Leaves are needle-like, 3-6 inches long, and bundled in pairs by a papery sheath (fascicle).

Male Pollen Cones

Male Pollen Cones are yellow, less than one inch long, and clustered at the tips of young shoots.

Female Seed Cones

Female Seed Cones are woody, sessile (lacking a stalk), somewhat shiny, and of a yellow-brown hue, often 2-3 inches in length and egg-shaped (Morton Arboretum, 2024).

Taxonomic History:

Pinus nigra was first described by Johann Franz Xaver Arnold (1785). The Austrian Pine has numerous described subspecies and varieties, with generally five currently recognized: pallasiana (Turkey and Crimea), dalmatica (Balkans), salzmannii (France and Spain), laricio (Corsica, Sicily and Calabria) and nigra (Alps) (Farjon, 2010). Pinus nigra has sometimes been confused for the species Picea mariana (formerly Picea nigra), due to the similarities in its name, though they differ dramatically in morphology, most notably in cone type. Picea mariana is a spruce (genus Picea) and not a pine (genus Pinus).

Identification Tips

In this park, Pinus nigra can be distinguished from other pines by needle length and fascicle (needle bundle) count. Pinus nigra has moderate-length needles that are 3-6 inches long and in fascicles of two. Pinus ponderosa has needles most often in fascicles of three, though it can be 2-5, but with needles 3-10 inches long. Pinus sylvestris also has needles in bundles of two, but with needles only 1.5-3 inches long, usually less than half that of Pinus nigra (Kral, 1993).

Fun Fact!

Pinus nigra is fast-growing compared to other pines, adding 13-30 inches in height a year, a trait preferred in the horticultural industry (Woodland Trust, 2024).

Fun Fact!

Austrian pine is susceptible to a variety of pests and insects, and generally discouraged from planting in the US Midwest due to its susceptibility (Morton Arboretum, 2024).

Plant Ecology/Habitat

Pinus nigra is native to Europe and North Africa. It prefers mineral-rich sandy soil and has been known to also grow in limestone. This hardy tree is quite tolerant of a variety of soils (Enescu et al, 2016).

Economic or Ethnobotanical Uses

  • Pinus nigra is commonly used for landscaping and as a shade tree, due to its hardy nature and tolerance of salted/sandy/dry soils (Morton Arboretum, 2024).
  • In its native Turkey, tar produced from Pinus nigra and its subspecies are widely used in medicine, particularly to treat topical wounds and infections, to seal wood from water damage, and as a repellant for snakes, mice, and insects (Ari et al., 2014).

Conservation Status

According to the IUCN red-list criteria Pinus nigra is rated as “Least Concern” regarding its conservation (Farjon, 2013).
