In ours, it feels like the speedwell is the winner, which I love.

@tomchadwin yellowrattle and yellow clover have a very firm foot hold!

You're laughing if you have yellowrattle. The wildflower ranger at NNPA broadcast it on potential wildflower sites because it's parasitic on grass, so it gives other flowers a chance. We have it in the verge up the lane, but it hasn't yet made it as far down as us, I think.

@tomchadwin I bought some from Emorsgate: https://wildseed.co.uk/. It's brilliant and has really helped control the grass, so other flowers can establish.

I don't even know yellow clover.

also called trefoil, according to plant.net.

I only know birdsfoot trefoil, which I'm pretty sure that isn't...
