Stan’s Notes: A widespread ash in Missouri. Also called Red Ash because it was once thought that the Green Ash and Red Ash trees were separate species. These are now considered one species. Not as water tolerant as the Black Ash (pg. 193), but able to survive with its roots under water for several weeks early in spring. Often has a large unattractive growth (insect gall) at the ends of small branches that persists on the tree throughout the year. The strong white-colored wood is used to make baseball bats, tennis racquets, skis and snowshoes.
