Dok yah is the Thai generic name for any kind of grass, including large types that can frequently be seen growing along roadsides, such as dok yah tong kong (ดอกหญ้าตองกง), known in English as bamboo grass and tiger grass (Thysanolaena latifolia) and which is used to make household brooms known as mai kwaat dok yah, which led to it also being nicknamed broom grass.
