Maple. Acer.
Premium grade Hard Maple (aka Sugar Maple) is a beautiful wood floor composed of both sapwood and heartwood, so there is color variation. Hard Maple has excellent resistance to abrasion and wear, making it ideal for high traffic areas. They make cutting boards out of hard maple for a reason! Hard Maple is also the wood of choice for ballroom and gymnasium floors.
Maple trees grown above the 38th parallel, as ours are, are renowned for their very tight and uniform grain—the result of the shorter growing season. This makes the wood of northern Maple trees extremely durable.
