Tree Audio Recording AvailablePurdue Plant Doctor Available Pinus bungeana [Lacebark Pine] Excellent specimen tree for bark interest, showing bark color on 1.5-2" dia. branches. Branches may break under snow. Attacked by many pine-targeting insects, with perhaps the Zimmerman Moth, the Pine Shoot Moth, and the Bud Moth being the most significant threat.

Tree Audio Recording AvailablePurdue Plant Doctor Available Pinus flexilis [Limber Pine] Large taproot makes it difficult to transplant once established. Generally low maintenance with few problems, but is susceptible to White Pine Blister Rust. Decaying needles acidify soil beneath (to about pH 4.5), which suppresses growth of other plant species.

Tree Audio Recording AvailablePurdue Plant Doctor Available Pinus flexilis 'Vanderwolf’s Pyramid' [Vanderwolf's Pyramid Limber Pine] 'Vanderwolf's Pyramid' is a vigorous grower with a strongly upright form and is common in the nursery trade. Large taproot makes it difficult to transplant once established. Generally low maintenance with few problems, but is susceptible to White Pine Blister Rust. Decaying needles acidify soil beneath (to about pH 4.5), which suppresses growth of other plant species. Audio Recording AvailablePurdue Plant Doctor Available
Tree Audio Recording AvailablePurdue Plant Doctor Available Pinus nigra [Austrian Pine] An excellent plant for screening when young. Needs a companion planting eventually for low screening as it loses branches at the base. Tolerates city conditions. Tolerates clay, dry, and alkaline soils, and heat. May be badly damaged by sapsuckers. Sphaeropsis tip blight is a more serious problem. Pine foliar nematode (transmitted by a beetle) can also be problematic.

Tree Indiana Native Audio Recording AvailableID That Tree Video AvailablePurdue Plant Doctor Available Pinus strobus [Eastern White Pine] 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 Pinus resinosa or Pinus nigra. Very sensitive to air pollution and road salt. Susceptible to White Pine Blister Rust.

Tree Audio Recording AvailablePurdue Plant Doctor Available 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.

Tree Audio Recording AvailableID That Tree Video AvailablePurdue Plant Doctor Available 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/Tree Audio Recording Available Platycladus orientalis [Oriental Arborvitae] Best in at least fairly moist soils, and with fairly high humidity. Habit tends toward becoming thinner (open) with age. Subject to "winter-burn" near the edge of its useful range. Certain forms provide very positive accent, but can be over-used. Bagworms can also be a problem. Audio Recording Available
