Fraxinus pennsylvanica

[Green Ash]

Produces many weed seedlings, except for seedless cultivars. An unattractive ash flower gall (formed by mites) can develop on male flowers and persists into winter. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented with the appropriate pesticide, but the treatment cost will eventually exceed replacement cost. See the Purdue Landscape Report article: Should ash trees still be protected from emerald ash borer? for more information.

Fraxinus quadrangulata

[Blue Ash]

The Blue Ash earned its common name from the blue dye early Americans made from its inner bark, which contains a substance that turns blue when exposed to air. This tree is naturally found upland in dry, rocky limestone areas and is very drought-tolerant. As with all ashes, Fraxinus quadrangulata is extremely susceptible to the Emerald Ash Borer.

Gleditsia aquatica

[Water Locust]

This native Indiana tree species is found in three southwestern counties near the lower Wabash River. It is often found in wet or ponded locations where there is standing water or high water tables. Not recommended for the landscape as it has large, multi-pronged thorns.  Like its cousin, the honey locust, it has compound leaves, but can be differentiated by its location, much smaller seed pods, and flattened thorns along the branches.
