Anti-growth grass – stays at a certain height and doesn’t need mowing

from quora – Several grass blends on the market are touted as no-grow mixes. The grasses tend to be blends of either fescues (Festuca) or bentgrass (Agrostis). One blend, Dwarf Fescue Lawn Seed Mix brands itself as a low-growing turf grass that is hardy in USDA zones 4 through 10. The No-Mow-Grass brand has two versions. The northern version is Creeping Bentgrass (Agrostis stolonifera), which is designed for areas with hard freezes, grows 3 to 6 inches tall and tolerates shade. The southern version is a blend of fine fescue and buffalo grass, designed for hot, dry areas. The No-Mow-Grass brand does not use USDA zones to classify its grass.
