When we talk about a hardwood floor, what are we actually talking about? As it turns out, a hardwood is not necessarily a harder material. It's not more dense or somehow stronger, and in the same way, a soft wood is not necessarily a softer material,
meaning less dense or softer or less strong. For example, balsa wood is one of the lightest, least dense woods. There is easily dented with your fingernail and it's considered a hardwood. So what's going on here. The distinction between hardwood and softwood actually has to do with plant reproduction. All trees reproduced by producing seeds, but the seeds structure varies. Hardwood trees are angious sperms, plants that produce seeds with some sort of covering. This might be a fruit like
an apple or a hard shell like an acorn. Soft Woods, on the other hand, are gymnas sperms. These plants let seeds fall to the ground as is, with no covering. Pine trees, which grows seeds in hard cones, fall into this category. In conifers, like pines, these eeds are released into the wind once they mature. This spreads the plants seed over a wider area. For the most part, angios sperm trees lose their leaves during cold weather, while gymnasperms
trees keep their leaves all year round. So it's also accurate to say that evergreens are soft woods and deciduous trees or hardwoods. The hardwood softwood terminology does make some sense. Evergreens do tend to be less dense than deciduous trees, and therefore they're easier to cut. While most hardwoods tend to be more dense and therefore sturdier, but as the classification of bostil wood demonstrates, there's no minimum weight requirement to become a hardwood.
