Tree InvasiveThis plant is considered invasive Pyrus calleryana 'Capital' [Capital Callery Pear] Overused, weak wooded, short-lived. Flowers are malodorous and often killed by late spring freezes. Forms narrow crotch angles that can result in a larger tree literally splitting in two. Very small fruits are a litter problem when abundant. 'Capital' is narrow-columnar in form and is severely susceptible to fireblight. The aesthetics of this cultivar decrease considerably with age. Considered invasive in many areas.

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 Indiana Native Quercus lyrata [Overcup Oak] The Overcup Oak is a medium-sized oak with an oval crown and lower branches that sweep upward. This species thrives in lowlands and bottomlands and can tolerate extended flooding. The common name is derived from its acorn, which can be nearly 3/4 "cupped" by the cap. Acorns generally aren't produced until the tree is around 25-30 years old.
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 muehlenbergii [Chinquapin Oak] More tolerant of city conditions than most oaks.
