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 no as desirable as pines. In youth it looks good but under hot, dry conditions may lose he 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 Acer × freemanii 'Scarsen' [sold as Scarlet Sentinel®] [Scarlet Sentinel Freeman Maple] This cultivar is a cross between the Red Maple and the Silver Maple, though it's leaves and bark more closely resemble the Silver Maple. It is one of the most adapted maples for southern regions of the country. 'Scarsen' is known for its colorful yellow-orange to orange-red fall foliage and columnar growth form.

The straight species has little to no disease or insect issues but some cultivars such as 'Flame' have issues with verticillium wilt. This species is widely adaptable to soil pH's and different types of soils and can be container plant. Unlike most Maples, the Amur Maple has fragrant yellow…
Tree Acer ginnala 'Flame' [Flame Amur Maple] This cultivar is similar to its straight species; Acer tataricum ssp. ginnala except for its fall color has a more vibrant coloration. Used similarly as the straight species, screening, mass plantings and patio plant are great uses for this plant. This cultivar can have issues with verticillium wilt as well.
Tree Indiana Native Acer negundo [Boxelder] Extremely tolerant of site conditions. Short-lived. Very weak-wooded. Invasive. Only use where nothing else will grow.
