Hardwood is wood from dicot angiosperm trees. Trees defined as hardwood trees are broad leaf varieties such as Oak, Ash, Beech, Sycamore etc.
Compared to softwoods they have a much more complex structure and as a result are often much slower growing.
The main feature that separates Hardwoods from Softwoods is the presence of pores/vessels. The vessels may vary in size, shape of perforation plates and structure of cell wall, such as spiral thickness.
Hardwood logs are a popular type of wood as they burn at a much slower, steadier rate giving off a much higher and longer lasting heat from your fire.
