Evergreens
When you use the word "softwood" you have to clarify whether you mean Gymnosperms (softwoods) or a wood that is soft, a soft wood. Take for example Balsa Wood used in model airplanes and such. It is very soft with a specific gravity around .18, but is actually a hardwood (angiosperm). Its scientific name is Ochroma pyramidale.
Slash Pine, Pinus elliottii, has an average specific gravity of .61 and is a "softwood" (gymnosperm) You could also say it is an "evergreen" It is harder than the Poplars, most of the Elms, the Willows, Cherry, and even some of the true Oaks, which are all hardwoods (angiosperms).
So you have got to be kind of specific when you say "hardwood" and "softwood".

Softwoods are typically produced by coniferous trees, such as pine, fir, spruce, and cedar. These trees have needle-like or scale-like leaves and bear cones that contain their seeds. Softwood is often used for construction, furniture, and paper production due to its straight grain and ability to grow quickly.
