Flowers
The flowers bloom from late summer to autumn and have 5 petals, usually pink, purple, or white with a streaky magenta V-shaped marking on the nose, but sometimes pure white with no markings.
The edges of the petals near the nose of the flower are curved outwards into strong
auricles. These are not present in some other species, such as ''Cyclamen persicum''. The flowers are occasionally fragrant. The shape of the flower varies from long and thin to short and squat.
