Quercus falcata
[Southern Red Oak]

Generally hardy only to zone 6, this oak is native to the southeastern United States, including the southern tip of Indiana, but can sometimes be grown in colder climates. This tree gained its specific epithet name, "falcata", from the sickle-like weapon of the same name, in reference to the sickle-shaped lobes of the leaves. Root disturbance is known to affect this species severely and can lead to decline or death.

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 is susceptible, but it is a minor problem. Unlike its relatives, the shingle oak's leaves do not feature any lobes and have a complete margin.
