Large, deciduous ash trees, Fraxinus excelsior, that grow throughout the temperate regions of Europe. Varieties include F. excelsior latifolia (weeping ash) and F.excelsior Diversifolia. European ash trees have a dense wood that is tough and elastic with a straight grain and slightly coarse texture. It is moderately durable but susceptible to insect attack. The timber is used for ladders, tool handles, oars, poles, wheels, boats, weapons, furniture, gymnasium equipment, tennis racquets, and hockey sticks.
