Botanically trees are classified as Hardwoods and Softwoods. The below article briefs about the various types of Wood Species.

Hardwoods

• Hardwoods are deciduous (broad-leafed).
• The most common Hardwoods are Birch, Cherry, Oak, Maple, Walnut, Hickory, Ashwood, Poplar, etc.
• They are
• – Deciduous in temperate climates
• – Lose their leaves in autumn
• – Old leaves are replaced by new ones in tropical climates.

Softwoods :

• Softwoods are coniferous (needle-shaped leaves).
• Common Softwoods are Pine, Western Red Cedar, Redwood, Cypress, etc.
• Softwood trees tend to grow more rapidly than hardwoods and also have larger less dense cells in the earlywood than hardwoods. The cell structure is less dense than hardwood, therefore a nail can be driven easily.
• – Mostly they are evergreen in various types of climates.
