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 Indiana Native Ulmus rubra [Slippery Elm] The Slippery Elm has a vase-shaped form, similar to that of the American Elm (Ulmus americana), but with more ascending branchlets. This tree gained its common name from the moist, slippery, red inner bark chewed by Native Americans and pioneers to quench thirst. Not considered very ornamental for the landscape, due to its coarse texture, weedy tendencies, and susceptibility to Dutch Elm Disease (although not as severe as the American Elm).

Shrub/Tree Indiana Native Viburnum prunifolium [Blackhaw Viburnum] Widely tolerant of different soils and exposures. Transplants well. Relatively trouble-free. Can be pruned to form a nice hedge. Scale and borers are occasional problems. The edible fruits are sweet and can be eaten fresh, or used in jams and preserves.
