Burchell's campion is a highly variable perennial herb occurring from the Western Cape northwards, throughout big parts of Africa and also in Arabia. A quick check of the literature has yielded at least eight recorded variations within this species, among them Silene burchellii var. angustifolia, var. cernua, var. gilletti and var. latifolia. The notched or V-shaped (five) petals of each flower tend to open wide or even turned back upon the long calyx. Leaf and calyx shape vary much.
