What is Bahia Grass?
Bahia grass is a tough, warm-season grass native to South America. It thrives in hot climates and is widely used in the southern United States for lawns, pastures, and erosion control. Bahia grass is known for its deep roots, drought tolerance, and ability to grow in poor soils.
There are two main types of Bahia grass commonly discussed: Argentine Bahia and Pensacola Bahia. Both belong to the species Paspalum notatum, but they have distinct characteristics that affect their performance.
Argentine Bahia: Characteristics and Uses
Argentine Bahia is a variety of Bahia grass that originated in Argentina. It is often recognized for its fine texture and darker green color compared to other Bahia types.
