Tree 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…
Tree Pinus strobus 'Fastigiata' [Columnar Eastern White Pine] 'Fastigiata' is a strongly narrow, upright cultivar. Excellent neutral screening plant, it can be kept full by occasional pruning. Among 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…
Tree Pinus strobus 'Pendula' [Weeping Eastern White Pine] 'Pendula' is weeping, semi-dwarf cultivar with long, pendulous branches. The ultimate form of this cultivar depends on how it is pruned and trained. More graceful than most pines, both as a young and an old specimen. Excellent neutral screening plant, it can be kept full by occasional pruning. Among 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…
Tree Pinus sylvestris [Scotch Pine] Effective as a screen with pruning. Tolerant of fairly dry soils, but not a good specimen in shade or on wet soils. Sphaeropsis, nematodes, and pine wilt fungus are serious problems; not recommended by Morton Arboretum.
Shrub Pinus sylvestris 'Hillside Creeper' [Creeping Scotch Pine] 'Hillside Creeper' is a low-growing, spreading evergreen that can be used as a groundcover. Tolerant of fairly dry soils, but not a good specimen in shade or on wet soils.
Tree Pinus thunbergii [Japanese Black Pine] The Japanese Black Pine develops a picturesque, open, and irregular form with age (excellent for bonsai), but pruning can be used to develop denser branching, if desired. This species is very tolerant of salt spray and is especially useful for coastal plantings. Pinus thunbergii is quite susceptible to Pine Wilt Disease from the Pine Wood Nematode (Bursaphelenchus xylophilus), which is vectored by the Pine Sawyer Beetle. Tends to have a shorter life span when grown…
