This member of the Fabaceae family was given this name by Carl Johann Maximowicz in 1873. It is found in Eastern China, Korea, Taiwan and Japan, growing in a rich but well drained soil with quite some water and some to lots of sun. The caudex can grow to five centimetres in diameter, the entire plant to two metres in height. The flowers are from greenish white over yellow to purple, and can have red edges. The genera name Apios comes from the Greek word, meaning 'pear' and may refer the pear shape of some tubers. The species is named after the Scottish botanist Robert Fortune. I am not sure, it will appreciate to have the rhizomes exposed? Photo by Wojciech Maksymilian Szymanski.
