Shrub Philadelphus lewisii 'Blizzard' [Blizzard Mock Orange] 'Blizzard' is a cultivar that is more cold hardy than the straight species. It is known for its white flowers that are very fragrant.
Shrub Philadelphus'Snowbelle' [Snowbelle Mock Orange] 'Snowbelle' is noted for having good heat and cold tolerance. It has minimal ornamental interest when not flowering.
Tree Picea omorika [Serbian Spruce] One of the most beautiful and valued spruces for landscape planting. More useful than most as a screen where space is limited because of narrow form. Needles can brown in windy exposed sites in winter. Can get aphids, budworms, and borers, though these are not usually serious problems.
Tree Picea orientalis [Oriental Spruce] Generally considered a better choice for the landscape than P. abies (Norway Spruce) or P. glauca (White Spruce). Best in cooler climates; does not always tolerate southern heat and humidity well. In order to prevent desiccation and needle browning, protection from harsh winter winds is advisable for plants grown in colder climates.
Tree Picea sp. [Spruce] The conical or pyramidal form of Spruces makes them a valuable addition to the landscape.
Shrub Pieris japonica [Japanese Pieris] Excellent large shrub specimen with handsome, lustrous, evergreen foliage, prominently red new growth in the spring, and small, interesting, urn-shaped flowers. Leaf spots, Phytophthora induced die back, and lace bug are most problematic. Struggles in alkaline and heavy, wet soils.
Tree 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 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 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.
Tree Pinus parviflora [Japanese White Pine] The species exhibits good salt tolerance. Although subject to rusts, wood rots, nematodes, and sawflies, none are serious.
