Poa pratensis, commonly known as Kentucky bluegrass, is a perennial grass species native to Europe, Asia, and North America. It is widely used in lawns, parks, and sports fields due to its lush green appearance and ability to withstand cold temperatures. This grass thrives in well-drained soils and prefers full sun to partial shade. The growth habit of Poa pratensis is characterized by its dense, sod-forming roots, which help prevent soil erosion. It produces fine, narrow leaves and can grow up to 24 inches tall. This species is also known for its ability to self-seed, contributing to its spread in suitable environments.
