Quercus acutissima, commonly known as the sawtooth oak, is a deciduous tree native to East Asia, particularly in regions like China and Korea. It typically grows to a height of 15 to 20 meters and features distinctive, serrated leaves that turn vibrant colors in the fall. The tree is valued for its rapid growth and adaptability to various soil types. The sawtooth oak produces acorns that are an important food source for wildlife, including birds and mammals. It is often used in landscaping and reforestation projects due to its resilience and ability to thrive in urban environments.
