Shrub Physocarpus opulifolius 'Seward' [sold as Summer Wine™] [Summer Wine Eastern Ninebark] Renew by cutting to the ground in late winter. Very course in texture in the winter with its multi-layered exfoliating bark (which gives it the common name of "ninebark"). 'Seward', generally sold under the name Summer Wine, has bronzy wine-red, more deeply cut leaves that may fade to green in hotter climates.
Tree Picea abies [Norway Spruce] Slight mite susceptibility in hot, dry sites. Some susceptibility to borers. May become thin, open, and have a less attractive habit at maturity.
Shrub Picea abies 'Clanbrassiliana' [Dwarf Norway Spruce] 'Clanbrassiliana' is a compact, flat-topped, mounded dwarf form. Slight mite susceptibility in hot, dry sites. Some susceptibility to borers.
Tree Picea abies f. pendula [Weeping Norway Spruce] As its common name suggests, the Weeping Norway Spruce has a drooping habit and pendulous branches. This plant's irregular form varies depending on how it is trained, and it may even spread along the ground if left unsupported. Slight mite susceptibility in hot, dry sites. Some susceptibility to borers.
Shrub Picea abies 'Nidiformis' [Bird's Nest Spruce] 'Nidiformis' is a commonly available dwarf cultivar that is flat, compact, and dense. Many times there is a depression or "nest" in the center of the plant. Slight mite susceptibility in hot, dry sites. Some susceptibility to borers.
Shrub Picea abies 'Pumila' [Dwarf Norway Spruce] 'Pumila' is a dwarf cultivar with a dense, flattend, globular form. The upper branches reach upward, while the lower branches spread outward. Slight mite susceptibility in hot, dry sites. Some susceptibility to borers.
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.
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 parviflora [Japanese White Pine] The species exhibits good salt tolerance. Although subject to rusts, wood rots, nematodes, and sawflies, none are serious.
