Softwood and hardwood are distinguished in nature in terms of their reproduction rather than their end appearance and attributes. In general, hardwood comes from deciduous trees which lose their leaves annually. Softwood comes from conifers, which usually remain evergreen. The trees from which hardwood is obtained tend to be slower growing, meaning the wood is usually denser.
Softwood allows the wood to light easily and burn hot and fast. A built fire will usually have large flames that crackle and spark along with a lot of smoke. Softwoods season faster than hardwoods and light much easier which makes them a popular choice for kindling.
Hardwoods are often considered to be superior firewood when comparing hardwood vs softwood because the wood is very dense.The dense wood creates a hot, long-lasting fire without a lot of smoke or sparks
