Dimorphotheca jucunda, the bergbietou in Afrikaans, is usually pink to mauve, i.e. the ray flowers commonly have those colours. There is, however, this white variety called white moon.
Flowers occur singly on long peduncles. The plant grows in summer rainfall grassland of the eastern parts of South Africa from Limpopo Province to Eastern Province, including a presence in Swaziland and Lesotho. The stems sprawl, branching from an underground base, but may also be somewhat erect. Apart from varying flower colour the leaves are also quite variable, sometimes succulent, sometimes toothed and inconsistent in shape, although usually long and narrow (Manning, 2009).
