Picea glauca, commonly known as the white spruce, is a coniferous tree native to North America. It typically grows in forests across Canada and parts of the northern United States. The tree can reach heights of 15 to 30 meters and has a conical shape with slender branches. Its needles are short, sharp, and bluish-green, while its cones are cylindrical and hang downwards. White spruce is valued for its wood, which is used in construction, paper production, and musical instruments. It also plays a crucial role in its ecosystem, providing habitat and food for various wildlife species.
