Tree InvasiveThis plant is considered invasive Pyrus calleryana 'Glen’s Form' [sold as Chanticleer®] [Chanticleer Callery Pear] Generally considered to be one of the best cultivars of P. calleryana. While still prone to limb breakage, it is stronger wooded than other variants. The Chanticleer Callery Pear is also known for its resistance to fireblight. Flowers are malodorous and often killed by late spring freezes. Very small fruits are a litter problem when abundant. Considered invasive in many areas.
Tree InvasiveThis plant is considered invasive Pyrus calleryana 'Redspire' [Redspire Callery Pear] 'Redspire' is one of the better P. calleryana cultivars, with a looser form and somewhat slower growth rate (less prone to limb breakage), but it does have severe fireblight susceptibility. Flowers are malodorous and often killed by late spring freezes. Very small fruits are a litter problem when abundant. Considered invasive in many areas.
Tree Pyrus salicifolia [Willowleaf Pear] The Willowleaf Pear is an uncommon, but elegant tree with arching branches covered with silvery, narrow, willow-like foliage. Attractive clusters of white flowers appear in the spring. Severe fireblight susceptibility.
Tree Indiana Native Quercus alba [White Oak] One of the most majestic trees at maturity with a picturesque framework, but requires many years to reach maturity. Long-lived, the kind of tree to use where it can be appreciated by succeeding generations. Slow growth eliminates it as a tree for quick effect. Roots are highly sensitive to disturbance, even foot traffic. Almost impossible to transplant from the wild. Often difficult to find in nurseries due to slow growth and recalcitrance to propagation by…
Tree Indiana Native Quercus bicolor [Swamp White Oak] The Swamp White Oak is a sturdy, long-lived tree that is generally tolerant to average conditions and even wet soil, but requires full sun and acidic soil.
Tree Quercus bicolor 'Bonnie and Mike' [sold as Beacon®] [Beacon Oak] 'Bonnie and Mike' is a cultivar with dense and glossy green foliage. Good for urban use with its tight upright columnar branching. It also has yellow fall color.
Tree Indiana Native Quercus coccinea [Scarlet Oak] Excellent scarlet fall foliage, comparable if not often better than the Pin Oak. Does not suffer iron chlorosis as bad as Pin Oak, being more tolerant of alkaline soils. Some report difficulty in transplanting.
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 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…
