Hunnh! I read of someone else on another website who never had trouble starting petunies ... until this year,
In my case they were almost all seeds from trades plus some F3 saved seeds.
Last year was F2 saved seeds.
The year before, a scattering of whatever cheap caught my eye in a rack.
The trade seeds this year were from many different kind people, many in the Hog Wild Piggy Swap (three great big oinks and a SOOOOIIEE for the HWPS!) I blame my soil mix, or something I did differently, not theier seeds.
Oh, I hope Star and tcs run it again this year, in cubits or here!
It's strange, because in the past I grew them too wet and too cold and around 150% of them germinated.
So this year i used better-draining mix and kepot their toes a little warmer - - - killing them.
Maybe the mix was just too coarse.
I even tried starting some "wild petunias" Ruellia nudiflora
- - - "Wild Petunia" (violet)
- - - Wild Petunia vars nudiflora, glabrata,hispidula (syn R. tuberose, Dipteracanthus nudiflorus) from LazLow
