I like warm, humid and sunny places, and require loose soil, good drainage and fertility, more greenhouse cultivation and flower viewing. Panicum miliaceum can grow into a subshrub in low latitudes. Born in wasteland, dry land, beside houses, sunny slopes, forest margins and grasslands.

Distributed in tropical and subtropical regions, widely cultivated in temperate regions; In China, Taiwan Province, Fujian, Guangdong, Guangxi, Yunnan, Guizhou and other provinces are often wild, Jiangsu and Zhejiang are mostly cultivated, and other provinces in the south of the Yangtze River and many cities in the north are cultivated. Usually born on sunny hillside grass or next to a house.
