Hardwoods and Softwoods

The terms ‘softwood’ and ‘hardwood’ do not indicate softness or hardness of particular timbers. In fact, some hardwoods are softer and lighter than softwoods. e.g. balsa The main differences between hardwoods and softwoods are botanical, and relate to the way the tree grows and the timber is laid down.
