I have grown Cerinthe from seed this year, but as there weren't many seeds in the packet I wondered if it would be worthwhile trying to collect them from my plants for next year?
Yes, large, black and easy to collect and grow. Will self seed as well
It was when I collected my cerinthe seeds that I realised just how extortionate seeds are to buy! I think I collected about 200 seeds and the original packet only had 12.
I have hundreds of collected seeds if anyone wants any. Mine have been gone for ages, you have been lucky to have them this long. You will find them popping up everywhere.
