American ash is similar in appearance to European ash. The sapwood is light coloured to nearly white and the heartwood varies from greyish brown to light brown, to pale yellow streaked with brown. The wood is generally straight grained with a coarse uniform texture.
The degree and availability of light coloured sapwood, and other properties, will vary according to the growing regions. For example, Southern ash lumber will be faster grown and contain more sapwood and therefore, a higher percentage of white colour, but compared to Northern ash, it has a more open texture and grain.
