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. 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).

Hard maple, growing naturally in the hardwood forests of North America, is world-renowned for its delicate colour, hardness, fine grain and finishing quality. American hard maple is a cold climate species although trees can grow throughout the USA. Forest Industry Analysis (FIA) data shows U.S. hard maple makes up 7.0% of total U.S. hardwood growing stock and that while 9.1 million m³ are harvested each year, more than 18 million m³ of American maple grows naturally across the U.S. hardwood forests each year.  The sapwood of hard maple is normally creamy white and the heartwood varies from light to dark reddish brown.  The wood has a close fine texture and is generally straight grained but can occur as ‘curly’, ‘fiddleback’ and ‘birds eye’ figure.  

American red oak is the dominant species in the U.S. hardwood forests with distinctive grain, and wood that is not always red in colour. The name is supposedly due to the leaf colour in the fall. Red oak trees grow only naturally and almost exclusively in North America, although planted elsewhere. Forest Inventory Analysis (FIA) data shows U.S. red oak growing stock is 18.7% of total U.S. hardwood growing stock and that while 33.9 million m³ of American red oak is harvested each year, more than 32 million m³ is naturally growing over the same period. In general the sapwood of red oaks is light brown and the heartwood is often pinkish to reddish brown. American red oaks have very good overall strength properties relative to weight. Its main uses are furniture, flooring, doors and certain construction applications.

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.

American yellow birch is grown sustainably with a wide distribution, preferring cool regions with high rainfall. Forest Inventory Analysis (FIA) data shows U.S. yellow birch makes up 1.5% of total U.S. hardwood growing stock and that while 1.85 million m³ is harvested per year, 2.62 million m³ of yellow birch grows naturally during the same period. Its wood has a distinct difference between the sap which is white and the heartwood which is light reddish brown. It is generally straight grained with a fine uniform texture. It is heavy, hard and strong and is used for furniture and joinery.
