• Identify a "rock" plant?

    This week I donated some of these offshoot rooted plantlets to a local
    bod setting up a folly/rockery. Then I realised I don't know what they are. Distinctive features seem to be able to live on nothing but air so I
    assumed a rockery would be similar.
    Colonised without human intervention from nowhere known, a clear
    polycarbonate roof of a shaded shed, seemingly just requiring a couple
    of mm of dust to root into and no water. Later colonising some old leaf
    litter on a concrete path. Until , as unlike say ivy, easy uprooting
    the plantlets only out of the dust/leaf litter, I'd not realised has
    very aromatic leaves.
    Earlier in the year dense mat of branching red stems and tiny white
    flowers preceeded by red pointed buds. My guess so far is some sort of oreganum .

    Possibly more likely to be something like /Thymus vulgaris/. Did you
    mean to supply a link to a photo?

    No pic as nothing of the runners than a few small whispy leaves each
    ond some very dry looking root mass.
    The distinctive red , like dogwood, of the matted red stems "dissolved "
    into general grey leaf litter by october.
    These spring/summer red stems looking like someone with a load of red
    wire frame models of polyhedra had squashed them all, tangled mesh of
    straight stem segments

    It sounds like something I have all over my garden. My identifier says
    it's called Herb Robert (geranium robertianum)

    The leaves are just right for herb robert and the red stems and smell
    and pointed flower buds, perhaps a stark white and smaller flowers
    variety of the pink flower form.

    I see for herb robert, the stems turn red for plants in full sun which
    is also the case here, shaded ones barely brown stems

    The habit you describe is exactly what I experience here. Plantlets form
    in the air but those which do root are very easy to pull up. You'd think
    it would be easy to get rid of it, but no! Back it comes every spring.

    By coincidence , I got up a ladder to clear the gutters. With the tile
    grit and moss blockages was growing loads of this plant, obviously
    perfectly happy up there. No trouble removing it as the roots don't root
    into anything structural unlike ivy, so if invasive then low in the
    scale of problematic.
    Loads more plantss for the local rockery-folly

    Actually they self-seed prolifically so all you need is a handful of seed.
