Fraxinus profunda, the pumpkin ash, is a species of ash (Fraxinus) native to eastern North America, where it has a scattered distribution on the Atlantic coastal plain and interior lowland river valleys from the Lake Erie basin in Ontario and New York west to Illinois, southwest to Missouri and southeast to northern Florida.[2][3][4][5][6] It grows in bottomland habitats, such as swamps, floodplains and riverbanks. It is threatened by the emerald ash borer (Agrilus planipennis), an invasive insect which has caused widespread destruction of ash trees in eastern North America.
