Shrub Abelia × grandiflora [Glossy Abelia] Glossy Abelia can develop chlorosis on high pH soils. Yearly pruning is required to remove deadwood and this plant may become leggy with age if not killed back in winter.
Tree Abies balsamea var. phanerolepis [Canaan Fir] The Canaan Fir is more tolerant of different environmental conditions than many other firs. It can tolerate wetter soils, and because of its later bud break, is more resistant to damage caused by late spring frost. Can be affected by spruce budworms, wooly adelgid, and several canker diseases, as well as deer. This species transplants well.
Tree Abies concolor [White Fir] Similar to Picea pungens f. glauca in color and general form, but less positive, and so easier to use in a variety of situations. Better adapted to hot, dry summers than most other firs.
Tree Acer buergerianum [Trident Maple] Needs training to develop single central leader (if that is desired). Popular street tree in Japan. Cold hardiness varies in seed produced stock. In some cases, fruit set is so high as to deplete foliage. Flaking bicolor bark in gray-brown and orange.
Tree Acer campestre [Hedge Maple] Transplants easily. Pruning may be needed to limb up branches to create a shade or patio tree. Tolerates severe pruning and soil compaction. Can be pruned to become a giant hedge.
Tree Acer grandidentatum 'Schmidt' [sold as Rocky Mountain Glow®] [Rocky Mountain Glow Maple] Acer grandidentatum is closely related to Acer saccharum (the Sugar Maple), which it is often compared to. This variant stands out due to its more upright form, smaller size, and its brilliant orange-yellow and orange-red fall foliage.
Tree Acer griseum [Paperbark Maple] Slow growth (6-12" per year) is compensated for by longevity and freedom from maintenance. The cinnamon-brown, curly bark is outstanding. Habit is open enough to display bark interest year-round.
Tree Acer japonicum 'Rising Sun' [Rising Sun Fullmoon Maple] This large-leaf maple provides a stunning fall-color around September to October with hints of orange, red and yellow earning it's cultivar name 'Rising Sun'.
Tree Acer miyabei [Miyabe Maple] Attractive bark is grayish with long, vertical scales and fissures in maturity. Some difficulty in both vegetative and seed propagation.
Tree Acer miyabei 'Morton' [sold as State Street™] [State Street Miyabe Maple] This selection has handsome corky bark with an oval form and attractive ascending branches. Acer miyabei 'Morton' is sometimes known as an alternative to Acer campestre, as it is more vigorous and cold hardy.
