The Fraxinus genus contains only a few species that are commercially harvested. Black Ash is one of them. It isn’t quite as dense or robust as the closely related White Ash (Fraxinus americana), which is due to its slower development rate, which results in a higher proportion of weaker earlywood sections. The closer ring spacing can also be utilized to tell the difference between Black and White Ash.

The color of the heartwood ranges from light to medium brown. Sapwood is often beige or light brown in color, and it is not always clearly or sharply distinguished from heartwood. The hue of Black Ash is a little darker than that of White Ash.

It has a medium to coarse texture that resembles oak. Although curved or figured boards are occasionally found, the grain is usually invariably straight and regular.

The heartwood is light to medium brown in tone. Sapwood is often beige or light brown in color, and it is not always clearly or sharply distinguished from heartwood. White Ash is a tad darker in color than Black Ash (Fraxinus americana).

Grain/Grain: Similar to oak, with a medium to coarse texture. Although curved or figured boards are occasionally found, the grain is usually invariably straight and regular.

Ring-porous endgrain; huge earlywood pores 2-4 rows broad, small latewood pores single and radial multiples; tyloses prevalent. The parenchyma around latewood pores is less common in Black Ash, yet it may be vasicentric, winged, and confluent; narrow rays, regular spacing

In terms of decay resistance, heartwood is classified as perishable or merely moderately durable. Insects aren’t very fond of ash.
