Norway Spruce (picea abies) are fast-growing, large evergreens known for their graceful, drooping branches (especially as it matures) and dark green, sharp, four-sided needles, making it a popular Christmas tree. Norway spruce trees are fast growers, typically adding 2 to 3 feet in height per year, especially when young and well-established in ideal moist, cool conditions, making them great for quick privacy screens and windbreaks. Growth slows as they mature, with many trees reaching their full height of 60 to 80 feet.
