What are the two groups of hardwood?

Hardwoods are typically classified into two main groups: deciduous and evergreen hardwoods. Deciduous hardwoods, such as oak and maple, lose their leaves annually and are often known for their broad leaves and varied colors. Evergreen hardwoods, like holly and live oak, retain their leaves throughout the year and generally have needle-like or leathery foliage. These classifications help in understanding their growth patterns and ecological roles.
