Echinopsis backebergii is a species of flowering plant in the cactus family Cactaceae, native to eastern Bolivia and southern Peru. It grows to 5 cm (2 in) tall and wide, with single or clustered globose stems 4-5 cm thick, with about 15 ribs and covered in grey-brown spines. Large, showy, carmine-red flowers are borne in summer. As the minimum temperature requirement is 10 °C (50 °F), in temperate regions it must be grown under glass with heat.
