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.
This hybrid from cross (S. johannis x S. ‘Elsi’) x S. ‘Ruby’ x S. ‘Elsi’) produced fantasy markings in two flowers from a peduncle of four. Other fantasy flowers in Streptocarpus can be seen here, here and here.
