Common Name: bahiagrass
Species: Paspalum notatum Flugge
Bayer Code: PASNO

Bahiagrass is a warm-season species that spreads by rhizomes, and is easily recognized by its characteristic "Y-shaped" seedhead. It exhibits low overall quality because of its light color, coarse texture, and open canopy. Due to its rapid lateral spread via aggressive rhizome production it is primarily used in areas where erosion control and immediate ground cover are the main concern. It is frequently planted on roadsides and highway rights of way because it has good drought tolerance. In addition, bahiagrass has the ability to tolerate a wide range of soils. Unfortunately, it can be a very competitive and unsightly weed in highly maintained turf.
