Heartwood in maple is not the same color as sapwood. The heartwood is wood that is no longer functioning to transport water to the crown. It is also a place where the tree dumps stuff that it does not need like extractives and such. Since the heartwood forms in the center of the tree, and the center of the tree was when the tree was young, this wood is called juvenile wood and has shorter wood cells, the wood cell walls are thinner, there is less cellulose in the cell walls, the angle of the cellulose chains in the cell walls is different, and the wood near the center of the tree is less stable, prone to more shrinkage, and definitely cracks and splits more than the mature wood on the outside of the tree, especially at the pith.

We have mostly red maple around here in central GA, and it has a blue-greenish colored heartwood. Very pretty like has been previously described. I have sawn and dried an lot of it. One of my very favorite woods to work with. Although it is called “soft” maple, it is not “soft”, having about the same density as walnut and ash, even denser than cherry. It is in fact a “medium hard” hardwood. Sugar maple is denser, and is one of the “harder” hardwoods.
