Tree Quercus × 'Crimschmidt' [sold as Crimson Spire™] [Crimson Spire Oak] The Crimson Spire Oak is notable for its powdery mildew resistance and reddish fall color that it gained from its White Oak parent, in addition to the dense, strong, vertical, columnar form, and tolerance to drought and urban conditions gained from its Fastigiate English Oak parent.
Tree Indiana Native Quercus × deamii [Deam Oak] The Deam Oak is a rare hybrid between the White Oak (Quercus alba) and the Chinquapin Oak (Quercus muehlenbergii) that can be found in mature forests. Quercus x deamii was first discovered in Wells County, Indiana, about 4 miles outside the town of Bluffton in 1904 by Bruce Williamson, a zoologist, and his father. Not sure what they had found, they took the specimen to Charles C. Deam who later sent the sample to his…
Tree Indiana Native Quercus ellipsoidalis [Northern Pin Oak] Quercus ellipsoidalis is very closely related to Q. palustris (Pin Oak), but is better suited for the Midwest. Very similar to the Pin Oak, the Northern Pin Oak is a handsome tree with distinctive and regular branching, spreading to horizontal to drooping, from top to bottom of the tree. This effect is partly lost when lower limbs must be removed for traffic underneath. While this species is still prone to chlorosis (yellowing of leaves) in…
Tree Indiana Native Quercus imbricaria [Shingle Oak] Somewhat tolerant of city conditions. Can be pruned into a hedge. Leaves persist into winter, after the normal leaf raking period, and then fall. Oak gall susceptible, but a minor problem.
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 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 'Pringreen' [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 Quercus robur × bicolor 'Nadler' [sold as Kindred Spirit®] [Kindred Spirit Hybrid Oak] 'Nadler' is a cultivar with a tight columnar form branching from the ground, adapted to many soil types, and a yellow-brown fall color.
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.
