What is Heartwood?

Heartwood is the dense, innermost part of a tree trunk, made up of dead cells that no longer transport water or nutrients. It is darker in color than the surrounding sapwood, and it is generally more resistant to decay, insect damage, and other forms of deterioration. Heartwood is often prized for its beauty and durability, and it is frequently used in woodworking and furniture making. Some common types of hardwoods that feature heartwood include oak, maple, and cherry.
