My Violetta came up well. Keep trying!
Sometimes one pot is slower than others. How long have they been in?
I saw a post earlier on another site which suggested that temperature fluctuations may help germination. Maybe a windowsill would work better? If you're on Facebook, there's plenty of expertise in the Kenosha Potato Project group.
If only I had one of those fancy propagators with temp control!Actually I doubt the temperature itself was a problem, since the other varieties germinated.
Apparently there are numerous Ratte-like strains around Europe under various names (this one's Russian Banana), and they rarely set seed. So the question is, does it come true, and will it produce berries? The more I have, the merrier!
It could be germination inhibitors. Fresh,, unfermented seed can be slow as the berry contains substances which prevent premature germination.
Another Violetta seedling is visible now, I might get some plants after all!
