Grows in valleys of Xianyang; now found everywhere, often in household gardens. Sprouts in spring, three to four chi high. Leaves are green like ox tongues and long. Stems are greenish-red, very soft and brittle. Flowers are red-purple and clustered in summer and autumn. Roots resemble radishes and are long, with red and white varieties; the white ones are used medicinally, while the red ones are toxic. Harvested in August and September.
