Picea is a genus of coniferous trees commonly known as spruces. These trees are characterized by their needle-like leaves, which are typically arranged spirally on the branches. Spruces are found in the Northern Hemisphere and thrive in cooler climates, making them a common sight in forests across North America, Europe, and Asia. They are valued for their wood, which is used in construction and paper production. Spruce trees can grow to impressive heights, often reaching 30 to 60 meters (98 to 197 feet). They produce cones that contain seeds, which are dispersed by the wind. Picea species, such as the Picea abies (Norway spruce) and Picea glauca (white spruce), are popular in landscaping and Christmas tree cultivation due to their attractive appearance and pleasant fragrance.
