Tree Picea pungens f. glauca 'Iseli Foxtail' [Iseli Foxtail Colorado Blue Spruce] 'Iseli Foxtail' is dense, upright, and columnar to pyramidal with new branches that resemble bushy fox tails. One of the most striking of the conifers in color and habit. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color does not combine well with other plantings in the landscape. Some…
Shrub/Tree Picea pungens f. glauca 'Montgomery' [Montgomery Colorado Blue Spruce] 'Montgomery' is a dwarf cultivar that forms a dense, silvery-blue, broad cone to mound. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
Tree Pinus cembra [Swiss Stone Pine] A fine formal specimen with age. Too slow growing to be very versatile, unless one is willing to purchase a large specimen. Susceptible to Zimmerman Moth, Pine Shoot Moth, and Bud Moth.
Tree Pinus densiflora [Japanese Red Pine] This species is outstanding for its landscape interest, making a uniquely picturesque specimen. Other species are better choices for screening.
Shrub/Tree Pinus densiflora 'Umbraculifera' [Dwarf Japanese Red Pine] This species is outstanding for its landscape interest, making a uniquely picturesque specimen. 'Umbraculifera' is an interesting dwarf cultivar, with a spreading, umbrella-like head and can be grown as a shrub or small tree. The flaky, orange-red bark of this plant is quite attractive.
Tree Pinus koraiensis [Korean Pine] Often confused with the Swiss Pine (Pinus cembra), the Korean Pine is a slow growing evergreen tree, native to eastern Asia. Pinus koraiensis is noted for its adaptability to many different environments and cold hardy. Its dark green needles have two white stomatal lines which gives the overall color of the needle a blue green. When young, the branching is tight and very pyramidal, which relaxes with age to a more loose pyramidal habit.
Shrub Pinus mugo 'Aurea' [Golden Dwarf Mugo Pine] 'Aurea' is a semi-dwarf cultivar with bright green needles that turn a bright golden-yellow in the winter. Best coloration in full sun. Pruning annually can help maintain dwarf habit (don't pinch or cut past candles). Can be disfigured by scale insects.
Shrub Pinus mugo 'Valley Cushion' [Dwarf Mugo Pine] 'Valley Cushion' is a very slow-growing (approximately 1.5" a year) dwarf cultivar that is excellent for rock gardens and bonsai. Can be disfigured by scale insects.
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.
