Hesperantha coccinea (kaffir lily, river lily or crimson flag; syn. Schizostylis coccinea Backh. & Harv.) is a flowering plant in the family Iridaceae, native to Southern Africa and Zimbabwe.
It is a semievergreen perennial growing to 60 cm (24 in) tall, with slender lanceolate leaves up to 40 cm (16 in) long and 1 cm (0.4 in) broad. The flowers are red, occasionally pink or white, 30–35 mm long, with six petals; they are produced four to ten alternately on a spike in late summer to autumn.
It is cultivated as an ornamental plant in gardens for its flowers, used in floristry. It is only hardy to between −5 to −10 °C (23 to 14 °F); in colder regions it is grown under glass. It is sometimes known in cultivation as "Kaffir lily". "kaffir" is considered an offensive ethnic slur in parts of Africa.
