Common Name: zoysiagrass
Species: Zoysia spp. 
Bayer Code: ZOYJA

Zoysiagrass is a warm-season grass that spreads by rhizomes and stolons to produce a very dense, wear-resistant turf. It is best adapted to the Piedmont and Coastal Plain regions of North Carolina, but some of the more cold tolerant cultivars can be grown in the western part of the state as well. There are three major species of zoysiagrass suitable for turf including Japanese lawngrass (Z. japonica), mascarenegrass (Z. tenuifolia), and manilagrass (Z. matrella). Zoysiagrass can often be confused with bermudagrass. However, zoysiagrass has hairs standing upright on the leaf blade whereas bermudagrass does not. Zoysiagrass is also stiff to the touch and offers more resistance than bermudagrass.
