Chris Rose once had an extensive Streptocarpus hybridizing program, resulting in a range of interesting cultivars. Most of them are no longer in cultivation, but it’s interesting seeing where he was going.
The “fantasy” color break in this cultivar is the subject of an article in the first 1998 issue of CrossWords, the newsletter of the Gesneriad Hybridizer’ Association. It is the result of a cross of a pink form of Streptocarpus cyaneus with the hybrid S. ‘Joanna’. A sibling seedling of this cross can be seen here.
