Tree Taxodium distichum var. imbricarium [Pondcypress] Can tolerate wet and dry soils. Does not tend to develop "cypress knees" like the Common Baldcypress.
Tree Tilia americana 'Redmond' [Redmond American Linden] Very adaptable, even in alkaline soil, but does not tolerate much air pollution. Too big for most urban landscapes. Japanese beetles like feeding on it.
Tree Tilia tomentosa [Silver Linden] Very adaptable, even alkaline soil, but it doesn't tolerate much air pollution. More heat and drought tolerant than other lindens. Japanese beetles are attracted to the foliage. Attractive light-gray, smooth bark approaches beech like in appearance.
Tree Ulmus americana 'Princeton' [Princeton American Elm] This American Elm cultivar retains the attractive vase-shaped form that the American Elm is known for and has some resistance to both the elm leaf beetle and Dutch Elm Disease, which is caused by Ophiostoma ulmi. (Dutch Elm Disease has lead to the near extinction of the American Elm in the US). Many other diseases can cause damage to this cultivar, though.
Tree Ulmus americana 'Valley Forge' [Valley Forge American Elm] This cultivar has the classic vase-like form and ascending branches that the American elm is know for, while also having the best Dutch elm disease resistance of the new "Dutch elm resistant" cultivars. Important to stake when young.
Tree Ulmus parvifolia 'Emer II' [sold as Allee®] [Allee Lacebark Elm] Stunning, multi-colored mottled and exfoliating bark, even on the surface roots. Tends to maintain foliage well during droughts. Grows well under city conditions. Resistant to Dutch elm disease and the elm leaf beetle.
Tree Ulmus pumila [Siberian Elm] Grows under almost any conditions, especially useful in dry sites. Resists Dutch elm disease. Leaf beetles can defoliate trees. Brittle branches and subsequently messy. Avoid planting this tree in the landscape, unless there is no other choice. Considered invasive in many areas.
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 Indiana Native Viburnum acerifolium [Mapleleaf Viburnum] The Mapleleafe Viburnum is a shade and drought tolerant plant that is excellent for naturalizing. Tolerant to the poison excreted by Black Walnuts.
