Pinus strobus 'Contorta'
Contorted Eastern White Pine

'Contorta' has a loose, irregular, upright form and twisted needles, branchlets, and branches. The Eastern White Pine is among the best pines for resistance to moth borers. Transplants easily with a bit of shade tolerance. Somewhat less adapted to severe exposures and very dry soils than Pinus resinosa or Pinus nigra. Very sensitive to air pollution and road salt. Susceptible to White Pine Blister Rust. Decaying needles acidify soil beneath (to about pH 4.5), which suppresses growth of other plant species.
