The Small balsam (Impatiens parviflora) belongs to Balsaminaceae (the Balsam family). It is an annual herb that is native to Central Asia, southwestern Siberia, and Mongolia. It has also become widely naturalized in other regions. It grows in riverbanks and damp areas, reaching a height of 30 to 60 cm. The stem is erect, fleshy, and has swollen nodes. The leaves are elliptical or ovate, with a pale green underside and a dark green upper surface, and have sharp serrations along the margins. From around June to August, it produces inflorescences from the upper leaf axils, bearing pale yellow flowers. The flowers are about 1 cm in diameter and feature straight nectar spur. The fruit is a linear-oblong or cylindrical capsule. In Chinese, it is called "小花風仙花" (xiao hua feng xian hua).
