Hi Tozi,
I have some ones, the same like your third pict., and a pure yellow one. And intermediate forms of the first, influenced by the yellow one, with the heart more or less yellow, and more or less big flowers...
But it is not a goog moment to send this species!
I really like these species, but their culture becomes difficult here, my climate becomes too hot and dry for them ... I used to sow their seeds produced by open polination, that explain the color variations of the two-color variety.
If you are interested by some swap, tell me
best regards
