Tree Indiana Native Quercus marilandica [Blackjack Oak] The Blackjack Oak is a small to medium sized tree with distinct, stout, irregular branches. It is very tolerant of poor, dry conditions, but does not tolerate wet conditions. This oak's common name is in reference to its dark, blackjack-like leaves.
Tree Indiana Native Quercus michauxii [Swamp Chestnut Oak] Similar to Quercus montana but obtains a larger ultimate size and is found in moister soils. Common in low areas, river bottoms, swamp borders and ravines. It gained its common name of "Basket Oak" from the baskets created from its wood, and the common name "Cow Oak" from the sweet, edible acorns relished by cows.
Tree Indiana Native Quercus montana [Chestnut Oak] Naturally grows in rocky places and poor, dry sites. Dislikes poor drainage. Bark has the highest tannin content of any Quercus species.
Tree Indiana Native Quercus muehlenbergii [Chinquapin Oak] More tolerant of city conditions than most oaks.
Tree Quercus nuttallii [Nuttall Oak] New growth is reddish purple with red fall color. A fast grower that prefers zones 7, 8, and 9.
Tree Indiana Native Quercus palustris [Pin Oak] Handsome tree, distinctive for its regular branching, spreading to horizontal to pendulous, from top to bottom of the tree. This effect is partly lost when lower limbs must be removed for traffic underneath. Requires an acidic soil and is subject to severe iron chlorosis on calcareous soils. This can be corrected but it means additional maintenance.
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 Quercus palustris 'Emerald Pillar' [sold as Green Pillar®] [Green Pillar Pin Oak] This cultivar is a columnar habit, great for those smaller spaces. Its fall color is a vibrant red, which leads many to believe that the Scarlet Oak, (Quercus cocinea) is in the genetics of this cultivar. Green Pillar Pin Oak is grafted onto root stock, so graft incompatibility may be an issue in the future. Requires an acidic soil and is subject to severe iron chlorosis on calcareous soils. This can be corrected but it…
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.
