BTW, Malva sylvestris is said to be Glyphosate-resistant.

It's also a bit big/upright for growing in lawns. Malva pucilla or M.
neglecta, maybe.

It survives in mown verges.

That doesn't surprise me, it's certainly very difficult to get rid of.
It manages to survive on the lawn lying flat and at the other extreme
will grow into quite a sizeable bush. It seems to me that it's much
commoner nowadays than it used to be.

We have white ones growing locally.

Would that be the white(ish) with pink veins, or a genuine white? Also,
wild, feral or cultivated?
