Having googled this, I'm confused: is it a hardy annual or a tender
(Mediterranean) evergreen perennial?
I know it self-seeds, and I've also saved seeds for next spring, but
should I pull the plants up, or cut them down, or might they look
reasonable through the winter in an otherwise bare bed?

I have the feeling that they might survive, but they usually look so straggly by
now that I tend to pull them up and start again next year with (self) seedlings.

I tried the yellow variety this year as well and was singularly unimpressed!
