Zoysia (UK: /ˈzɔɪziə/;[3][4] US: /ˈzɔɪsiə/, -/ziə/, -/ʃə/, -/ʒə/[3]) is a genus of creeping grasses widespread across much of Asia and Australia, as well as various islands in the Pacific.

These species, commonly called zoysia or zoysiagrass, are found in coastal areas or grasslands.

Zoysia grasses stop erosion on slopes, and are excellent at repelling weeds throughout the year.

In typical savanna climates with warm wet and dry seasons, such as southern Florida, zoysia grasses grow during the warm-wet summer and are dormant in the drier, cooler winter months.

In contrast to St. Augustine grass, they generally require less fertilization and are less vulnerable to insect and fungus damage, depending on environmental conditions.
