Gentiana triflora explained

Gentiana triflora (三花龙胆 san hua long dan in Chinese, called clustered gentian in English) is a tall, flowering perennial plant in the genus Gentiana native to higher-elevation (600–1000 m) meadows and forests of China (Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol), Mongolia, Eastern Russia, Korea and Japan.^[1]

Gentian blue petals predominantly contain the unusually blue and stable anthocyanin gentiodelphin (delphinidin 3-O-glucosyl-5-O-(6-O-caffeoyl-glucosyl)-3′-O-(6-O-caffeoyl-glucoside)).^{[2] [3]}
