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.
Shrub Physocarpus opulifolius 'SMNPOTW' [sold as Tiny Wine®] [Tiny Wine Ninebark] Tiny Wine Ninebark is noted for its features as it is interesting season round. The exfoliating bark on mature wood reveals red-brown inner bark, this is how the common name Ninebark was chosen as the color is ever changing.
Tree Picea glauca [White Spruce] Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Often found at the arctic tree line. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites. Except for its use in the far North, other evergreens have better overall aesthetics for Midwestern and Eastern states.
Shrub/Tree Picea glauca var. conica [Dwarf Alberta Spruce] This commonly available dwarf variety has a very dense, conical habit. Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites. Except for its use in the far North, other evergreens have better overall aesthetics for Midwestern and Eastern states.
Tree Picea glauca var. densata [Black Hills Spruce] Widely considered a superior form, this variety is denser and more compact with brighter foliage, when compared to the straight species . Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites.
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 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 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.
