Blue ash in the landscape
Fraxinus quadrangulata, or blue ash, is a native tree you would not be likely to stumble upon by accident, and I was suspicious when I was called to look at a back-yard tree that the homeowner had identified as this species -- and just a few blocks from Arborland no less. But there it was, all ash-like but with bark that was puffed up like Meg Ryan's lips. A lovely specimen. You can usually tell blue ash by the corky ridges on the twigs, but in this case that character was lacking. However the samaras (winged seeds) had obviously read the field manual. Blue ash seems to have some resistance to emerald ash borer, and it is often just disfigured rather than killed outright. The homeowner had been injecting his specimen annually with orthene/acephate, which seems to have done the trick. In the wild, blue ash can be found on rich moist soils in Bird Hills Park, Lower Huron Metro Park and the Sharon Hollow Reserve.
