Tree Ulmus americana [American Elm] American Elm, also known as White, Gray, Water, or Swamp Elm. Previously, a common street tree but the Dutch elm disease killed many trees. Although, with maintenance programs some trees are able to hold back the disease.
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 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).
