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.
Tree Ulmus minor [Smoothleaf Elm] Moderate 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.
Tree Ulmus parvifolia [Lacebark Elm] Stunning, multi-colored mottled and exfoliating bark. Grows well under city conditions. Good resistance against Dutch elm disease, elm leaf beetle, and Japanese beetle. Slightly weak wooded, so sometimes damaged by ice storms.
Tree Ulmus parvifolia 'Burgundy' [Burgundy Lacebark Elm] This cultivar is noted for outstanding habit and foliage. Stunning, multi-colored mottled and exfoliating bark. Grows well under city conditions. Good resistance against Dutch elm disease, elm leaf beetle, and Japanese beetle. Slightly weak wooded, so sometimes damaged by ice storms.
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 parvifolia 'UPMTF' [sold as Bosque®] [Bosque Lacebark Elm] Stunning, multi-colored, mottled, and exfoliating bark. Grows well under city conditions. Good resistance against Dutch elm disease, elm leaf beetle, and Japanese beetle. Slightly weak wooded, sometimes damaged by ice storms.
Tree Ulmus × 'Patriot' [Patriot Elm] 'Patriot' is a cultivar with high resistance to elm leaf beetles and Dutch elm disease. It also has some resistance to elm yellows. It has green leaves that have a glossy texture and turn yellow in the fall. It is used many times as a street tree due to its fast-growing nature and its road salt tolerance.
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).
Tree Ulmus sp. [Elm] The Elm genus, Ulmus, contains about thirty species of mostly deciduous trees. Generally susceptible to 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).
