Shrub Pinus mugo var. pumilio [Dwarf Mountain Pine] The Pinus mugo var. pumilio dwarf shrub is found in the wild in the mountains of eastern and central Europe. The shrub can spread up to 10' wide but typically stays short in height, 3'-5' at maturity. Avoid planting in poorly-drained wet soils.
Tree 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.
Shrub Pinus nigra 'Hornibrookiana' [Dwarf Austrian Pine] 'Hornbrookiana' is a compact and mounded dwarf cultivar. 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 Pinus ponderosa [Ponderosa Pine] Pinus ponderosa is a very tolerant tree, adaptable to a wide range of conditions, except for shade and poor drainage. Older trees often lack lower limbs. It is dominant in western North America, where it can reach up to 230 feet tall, and is an extremely important timber tree.
Tree Pinus resinosa [Red Pine] Forms a decent screen when young, especially on poor, dry soils, but soon drops lowers limbs necessitating the need of companion plants to complete the screen. Develops a shorter, thicker trunk when grown in the open. Pine bud moth (as well as other moths) can be problem if not controlled. Foliage presentation not always full or clearly esthetic. Best in groves or plantations where bark color can be admired.
Tree Pinus rigida [Pitch Pine] Pinus rigida is native to the poor, sandy upland soils of eastern North America. The falling needles, cones, branches, and sap can be problematic. This plant is not generally recommended for use in the landscape, except on very poor soils. Best grown in a solitary location, where it won't be forced to compete with nearby plants.
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…
Tree Platanus × acerifolia [London Planetree] Platanus x acerifolia is quite similar to P. occidentalis, but was originally advertised as being much more pest resistant. P. x acerifolia was quickly overplanted, and it is clear that pest resistance varies among hybrids, and can be quite poor. Pests that can severely affect this species include sycamore anthracnose, cankerstain, Botryosphaeria canker, leaf spot, powdery mildew, sycamore lace bug, and American plum borer. One of the largest of shade trees, making massive, majestic specimens.…
