    They're spiderweb sempervivums. The pups can be tiny so maybe it came in with another plant or there may have been seeds in the soil.
    If you can keep your head, while those around you are losing theirs, you may not have grasped the seriousness of the situation.

    Thanks @wild edges. I like them and they've plonked themselves in a good place. Haven't bought any sempervivums for many years so they must've been lurking in the soil. How long would they have taken to get to that size?

    Usually they offset from the parent plant in the autumn and then flower themselves to death the next summer. I'm not sure how long it takes from seed though, or if they're detached early from the parent plant. Add another year I suppose. I don't really pay that much attention to them but the growth and life cycle rates do seem to vary a lot.

    I'm surprised I hadn't noticed it before. I just pick out the odd weed and spray with water if I think of it, which isn't often so I suppose they could've been there for a while.

    Your "keen" is showing, but also your "lazy".  Sempervivums were born for the latter.  Keep up the benign neglect.

    Have you replanted them?  They seem to be in ideal conditions, and with sedum company as well.

    The spider web forms seem to be less hardy than some of the others. Not sure why maybe water collects in the webs?

    A nice easy to remember botanical name too - Sempervivum arachnoideum 🙂

    @bédé the weeds and strawberry  plants growing out of the patio under the bench are true testament to my laziness. The handle of the loppers  shows that  du temps en temps, I can bestir  myself😏
    They planted themselves. I only noticed them today.

    Fabulous.  

    Weeds and strawbwrry plants; you mean intentional groundcover, of course.

    Obviously too lazy to repair your pots.  But I think you need to change your "keen but lazy" tag.
