Tree Indiana Native Quercus muehlenbergii [Chinquapin Oak] More tolerant of city conditions than most oaks.
Tree Indiana Native Quercus pagoda [Cherrybark Oak] Generally only hardy up to zone 6, this oak is larger than the closely related Southern Red Oak (Quercus falcata) and prefers wetter sites. It is native to southeastern regions of the United States and naturally grows as far north as southern Indiana and Illinois.
Tree Quercus palustris 'Crownright' [Crownright Pin Oak] Handsome tree with a more upright habit that lacks the pendulous character of the lower branches seen in the species type. Requires an acidic soil and is subject to severe iron chlorosis on calcareous soils. This can be corrected but it means additional maintenance.
Tree Indiana Native Quercus phellos [Willow Oak] Somewhat tolerant of city conditions. Oak wilt and scales, and many other oak tree pests, though none considered very serious. Low maintenance, long-lived tree. Use Northern sources in Indiana.
Tree Quercus robur 'Fastigiata' [Columnar English Oak] The tightly columnar 'Fastigiata' provides a strong vertical accent, and is far more popular in the Midwest than the straight species. Powdery mildew on the leaves can be a significant problem. Seed propagated 80-90% true to type, thus variation can also be a problem.
Tree Indiana Native Quercus shumardii [Shumard Oak] The Shumard Oak is a handsome tree that is drought and air pollution tolerant, and but can also be used in rain gardens. Transplanting and establishment can be difficult.
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.
