Hi Kevin,
so the number of chromosome sets will remain unknown in my non-named variaties as I neither have a mikroscope nor a real comparison for plant and pollen size...bigger is so relative...
As a starter my aim is F1 - if the crosses should work I will give F2 a try. I'm not planning to sell anything - I'm just curious what happens...A dark red to black xjovibarba hirta would look awesome don't you think?...
Have a nice afternoon!
Regards,
Michael
