Tree Abies balsamea [Balsam Fir] Used mainly as a specimen tree and popular as a Christmas tree. Does not hold its needles very long in a dry house and for this reason is not as desirable as pines. In youth it looks good but under hot, dry conditions may lose the older needles and become open and unkempt.
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 Abies concolor 'Blue Select' [Blue Select White Fir] Better adapted to hot, dry summers than most other firs. 'Blue Select' is noted for its intense blue upright needles.
Tree Abies concolor 'Conica' [Conica White Fir] 'Conica' is a narrow habit white fir, with a spread reaching 10-15' wide. Similar to Picea pungens f. glauca in color and general form, but less positive, and easier to use in a variety of situations. Better adapted to hot, dry summers than most other firs, but prefers cooler cilmates.
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 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 × 'Hipzam' [sold as Highland Park®] [Highland Park Bigtooth Maple] Acer grandidentatum is closely related to Acer saccharum (the Sugar Maple), which it is often compared to. 'Hipazam', often sold under the name of Highland Park, is an upright variant with an oval crown and lustrous, deep green leathery leaves that turn an attractive orange-red in autumn.
