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 InvasiveThis plant is considered invasive 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.
Shrub Viburnum burejaeticum [Manchurian Viburnum] The Manchurian Viburnum is an uncommon species similar to Viburnum lantana (Wayfaringtree). A very adaptable shrub with good flower production, fruit set, and fall color. Grows remarkably fast in the spring.
Shrub Viburnum lantana [Wayfaringtree Viburnum] The Wayfaringtree is a coarse-textured large shrub noted for its abundance of showy flowers and colorful fruits. Plant in groups with different clones for best fruit set. Has escaped cultivation and naturalized in some areas of the United States.
Shrub Viburnum × 'Pragense' [Prague Viburnum] More drought tolerant than most Viburnums. Topping may be needed initially to encourage branching. This hybrid arose in Prague, Czechoslovakia in the 1950s.
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.
Shrub Viburnum prunifolium 'Mrs. Henry Large' [Mrs. Henry Large Blackhaw Viburnum] 'Mrs. Henry Large' is quite rare and unlikely to be found in commerce. 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.
Liana (Climbing Vine) Wisteria sinensis [Chinese Wisteria] Tolerant of widely different conditions once established, but this plant does not like being transplanted and establishment is sometimes slow. Once established, though, can even become invasive. Can be pruned as a standard, or pruned nearly to the ground to rejuvenate. Prune after flowering to 6" of main branch, and if pruned later, avoid removing the fatter flower buds that develop later. Needs a strong support structure. Use plants propagated vegetatively from heavy-flowering clones, as…
