What type of trees are classified as a source of hardwood?

Hardwood is primarily derived from deciduous trees, which are those that lose their leaves annually. These trees typically have broad leaves and include species such as oak, maple, cherry, and walnut. Deciduous trees generally have a denser and more complex structure, which contributes to the durability and strength associated with hardwood. This wood is often used in furniture, flooring, and cabinetry due to its appealing grain and workability.

Coniferous trees, on the other hand, are generally classified as softwoods. These trees, like pines and spruces, retain their needles and cones throughout the year. While they can be strong, they generally do not match the density and durability of hardwoods. Palm trees, while they may produce wood, are classified as monocots and do not fall under the traditional hardwood category. Evergreen trees refer to trees that retain their leaves year-round, which can include some conifers as well.

Thus, the classification of deciduous trees as a primary source of hardwood reflects their unique properties in comparison to other types of trees, which either do not produce hardwood or do not fit the typical characteristics associated with hardwoods.
