Spruce trees are evergreen conifers belonging to the genus Picea. They are characterized by their needle-like leaves, which are typically sharp and stiff. Spruce trees can grow tall, reaching heights of up to 200 feet, and are commonly found in northern regions of the world, including parts of North America and Europe. These trees produce cones that hang down from their branches, and their wood is valued for its strength and versatility. Spruce wood is often used in construction, furniture making, and for producing musical instruments, such as guitars and violins.
