‘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 […]
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. […]
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 […]
‘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. […]
The species exhibits good salt tolerance. Although subject to rusts, wood rots, nematodes, and sawflies, none are serious. […]
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. […]
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 […]
This species is outstanding for its landscape interest, making a uniquely picturesque specimen. Other species are better choices for screening. […]
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. […]
‘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 […]
