Had these in a bed last year and assumed they would self-seed. By June
nothing had happened, so I moved other things into the gaps - and now
the bed is full of cerinthe seedlings, all but one only still at the
two-leaf stage. Surely at this stage they are unlikely to mature - but
then what is the purpose of self-seeding?

Don't forget they're not british. In the Med, they would want to
germinate at the end of a hot spell when the autumn rains are starting.
