American ash is ideal for bending and turning – and is strong and tough with distinctive grain, character and colour. It grows commonly throughout the eastern United States in mixed hardwood forests. Forest Inventory Analysis (FIA) data shows U.S. ash makes up 5.1% of total U.S. hardwood growing stock in the forest and that while 6.1 million m³ of American ash is harvested each year, the forests are naturally growing 12.1 million m³ during the same period. It has light coloured wood, with sapwood varying from white to yellow and heartwood ranging from light to dark brown. Being very hard, stable when dry and easy to finish and stain, it is ideal for furniture and flooring.

Commercially American tulipwood, known domestically as yellow poplar, is one of the most prolific hardwood species from the U.S. hardwood forests and is unique to North America. Forest Inventory Analysis (FIA) data shows U.S. tulipwood makes up 7.7% of total U.S. hardwood growing stock and while 12.8 million m3 are harvested each year, more than 32 million m³ of American tulipwood grows naturally in the hardwood forests during the same period. Tulipwood has less strong grain characteristic than species such as ash and oak and exhibits a marked difference between the sapwood and heartwood. The sapwood is creamy white whereas the heartwood can vary from pale yellow or brown to green and purple in extreme cases. The wood darkens on exposure to light. American tulipwood has extraordinary overall strength properties relative to weight, making it highly suitable for structural applications, such as glue-laminated beams and cross laminated timber (CLT).
