Sedum acre - has little yellow flowers.

Thanks, not seen it in flower, wiki says it struggles to outcompete
other plants, but it seems to be doing a very good job of outcompeting
most things on cleared ground ...

It thrives on seriously poor ground that doesn't hold water, where
most plants don't. It's a bit like my Cyclamen coum, which has
(with very little assistance) formed a monoculture in a bed that is
under the eaves of my house. Neither will do that if there is any
serious competition from faster-growing plants.
