Shrub Taxus × media 'Anthony Wayne' [Anthony Wayne Anglojap Yew] 'Anthony Wayne' is an interesting columnar, female cultivar that has strongly upward growing shoots tipped with bright green new growth. Withstands nearly any amount of pruning. Black vine weevil can be a problem, but this is rare. Newly planted yews do not perform well in poorly drained soils. Perhaps overused in the urban landscape. Can be severely damaged by deer.
Tree Thuja plicata 'Elegantissima' [Elegant Giant Arborvitae] One of the best plants for screening when grown in wet, but not saturated soils. An important timber tree in the western US. Subject to several pests (especially bagworms), all of which usually can be controlled with timely spraying.
Tree Thuja plicata 'Green Giant' [Green Giant Arborvitae] Green Giant Arborvitae is one of the best plants for screening when grown in wet, but not in saturated soils. The straight species was an important timber tree in the western US. Subject to several pests (especially bagworms), all of which usually can be controlled with timely spraying.
Tree Tilia cordata 'Glenleven' [Glenleven Littleleaf Linden] 'Glenleven' is a fast-grower with a strong, straight central leader, more open canopy, and larger leaves. Never colorful, but a good shade tree that is well-adapted to most city conditions and relatively troublefree. Functions as a small tree for many years. Japanese beetles can feed heavily on foliage beginning in mid-summer.
Tree Indiana Native Tsuga canadensis [Canadian Hemlock] One of the finest plants for evergreen hedges; even the faster growing forms can be kept to 4-8' tall without difficulty. Dwarf forms are excellent rock garden or border specimens. Foliage browns in dry soil, drying wind, and winter sun in very exposed sites. Does not tolerate long periods of drought. Can be scorched by full sun and temperatures above 95 degrees F. Many minor pest problems, with wooly aldelgids being especially serious in the…
Tree Tsuga caroliniana [Carolina Hemlock] Slower growth than Tsuga canadensis and less variable in size and form. Performs better under city conditions than T. canadensis. Still, like T. canadensis, foliage browns in dry soil, drying wind, and winter sun in very exposed sites, and it does not tolerate long periods of drought. Can be scorched by full sun and temperatures above 95 degrees F. Many different kinds of minor pest problems.
Tree Ulmus davidiana var Japonica 'Morton' [sold as Accolade®] [Accolade Elm] Very good resistance to the Dutch elm disease pathogen, Ophiostoma ulmi, which has led to the near extinction of the American Elm (Ulmus americana) in the U.S. Also has good resistance against phloem necrosis, elm leaf beetle, and leaf miner.
Tree Ulmus davidiana var. japonica 'Prospector' [Prospector Elm] 'Prospector' is a cultivar with an excellent resistance to Dutch elm disease (DED) and smaller than american varieties. It is fast growing and requires maintainance to keep its vase shape, but works well as a street tree. It has showy emerging leaves and a brilliant yellow fall color.
Tree Ulmus × hollandica 'Pioneer' [Pioneer Dutch Elm] Resistant to Dutch elm disease and phloem necrosis, but susceptible to the elm leaf beetle.
Tree Ulmus × 'Homestead' [Homestead Elm] Dutch elm and phloem necrosis resistant, but susceptible to the elm leaf beetle. 'Homestead' was formed from a cross between Ulmus minor, U. x hollandica, and U. pumila.
