cerinthe seeds, when to gather
I recently posted a picture of a lovely plant I'd seen in a local bank, and it was identified by helpful posters as cerinthe. Looks like growing from seed is the way to go. The one in the bank is currently in flower - when should the seeds be ready to gather? As I'd like to try collecting a couple and growing them on for my garden. I don't want to go looking for them and find they've already fallen!
