I have some self set, but I always collect a few seed to push in 3inch pots for gap filing
. I currently have a forest of self set Cerinthe major purpurascens, which I might pot up a few small ones to overwinter in the greenhouse, but I bet the big ones don't get to flowering stage before the frost gets them.
The hot then wet then hot weather seems to have triggered quite a few seeds to grow prematurely. I have quite a few seedling of Verbena bonariensis to pot up and overwinter indoors too.
