Streptocarpus johannis is an important species in the development of the popularity of the genus. It was a contributor to some of the earliest widely-grown hybrids, such as S. ‘Constant Nymph’, and features in the background of many hybrids.
It is a highly variable species, with multiple flower forms and plant sizes, as well as variable amounts of blue in the flower. There are white forms and bright blue forms, with and without lobe markings.
The plant shown above fairly accurately reflects the pale blue color of many species variants; it’s often difficult to get this color exactly right, so expect some variety in the photos in the links.
