Timber used for construction can generally be split into types, namely softwood or hardwood.
The classification of timber into softwood and hardwood can be misleading since some softwood trees tend to be hard while some hardwood trees tend to be soft. Balsa wood is a deciduous species of angiosperm and as such it is classified as a hardwood but it is actually very soft! To differentiate between these two types of trees it is best to remember that they have different properties and as such their use in construction depends on the needs of the homeowner. Essentially, the difference between softwoods and hardwoods lies in their cellular structure.
From the description above, we can see that the terminology used to classify trees does not make much sense. Hardwoods are dense and harder to cut while evergreens are less dense than deciduous species and they are thus more easy to cut. As Balsa wood demonstrates, there is no weight requirement for a tree to be classified as a hardwood.
