A fir tree is a type of evergreen coniferous tree belonging to the genus Abies. These trees are known for their tall, straight trunks and needle-like leaves that remain green throughout the year. Fir trees are commonly found in mountainous regions and are popular for their use as Christmas trees due to their symmetrical shape and pleasant fragrance. Fir trees produce cones that hang down from their branches, which is a distinguishing feature. They thrive in well-drained soil and can grow in various climates, making them adaptable. Some common species include the Noble Fir and Fraser Fir, each valued for its unique characteristics.
