The Tree

Ashes are trees or shrubs with large, opposite, pinnately compound leaves, which are shed in the fall. The compound leaves have 2 to 11 leaflets. The flowers can be bisexual or there can be distinct male and female flowers on separate trees. The flowers have no petals and the fruits are dry with a flattened wing.


The sapwood of ash is light brown, while the heartwood is brown to grayish brown. White Ash and Oregon ash has lighter heartwood than the other commercial species. The width of the sapwood is 3 to 6 inches. It is ring porous, with the latewood being composed of parenchyma which surrounds and unites the latewood pores in tangential bands. It has no characteristic odor or taste.


Ash is straight grained, heavy, hard, strong, stiff and wears smooth with high shock resistance.
