Lespedeza thunbergii is a species of flowering plant in the legume family known by the common names Thunberg's bushclover, Thunberg's lespedeza, and shrub lespedeza. It is native to the eastern Himalayas, China, Korea, and Japan.[2]

This species produces annual stems up to 2 m (7 ft) tall and 0.5 in (1.3 cm) in diameter. They die back completely at the end of the season. The abundant pink to purplish flowers bloom in late summer. The fruit is a legume pod containing black seeds.[3]

Five subspecies are accepted:[1]

  • Lespedeza thunbergii subsp. elliptica (Benth. ex Maxim.) H.Ohashi – eastern Himalayas to central China
  • Lespedeza thunbergii subsp. formosa (Vogel) H.Ohashi – southeastern China, Taiwan, Korea, and Japan
  • Lespedeza thunbergii subsp. patens (Nakai) H.Ohashi – Japan (northern and central Honshu)

The specific epithet thunbergii refers to the 18th-century Swedish botanist Carl Peter Thunberg.[4]
