Shima Gōbō

Rumex wrightii | Okinawan Wild Burdock

Botanical Description

Unlike the commonly cultivated Arctium lappa burdock in mainland Japan, Shima Gōbō refers to a wild Okinawan plant known botanically as Rumex wrightii. Though called “burdock,” it is not a true Gōbō but has similar culinary and medicinal qualities. It grows in coastal or disturbed areas, with long taproots and tall flowering stalks.
