I'm coming to the conclusion this 'wildflower meadow' thing only works if you happen to be on a certain sort of soil, and you're probably better accepting what wants to grow there (except fecking ground elder) to an extent and maybe encouraging what does grow.
We'll have been in this garden for 2 yrs come August. Not a lot grew in our no mow lawn last year except a small patch of clover and a little bit of self heal at the wet (but sunny) end of the garden. Nothing grew in the section I was originally going to leave for no mow. Mind you not even the grass really grew. Some stuff got tall but not most of the lawn.
This year the clover has really spread a lot round where it was and to other patches of the lawn, and I'm ok with that because the bees love it. There's quite a bit of moss in some places but that's ok, it must support something. And birds like moss in their nests.
The self heal is marching into borders but I plan to dig that up and try to plant plugs of it at the other end of the garden.
There is creeping buttercup, which I don't really want in
my borders but I suspect I will struggle to control without weedkiller. But I don't really mind if it wants to grow in the lawn.
There were Welsh poppies growing here already, at the edges of the garden, not in the lawn, so I tried spreading them round a bit when they went to seed last year.
This year I've tried planting some yarrow plugs in one area, but only as an experiment because I happened across them at the garden centre.
I also got a stack of wildflower seed last month, some of which is to go in the shady boggy area that is currently drowning some lavender, mostly just as a suck it and see though.
I threw some cornflower seed in one section of bed as well but the cat keeps sitting on there waiting for mice to turn up so it's probably been eaten by nice, birds or squashed by cat.
I wouldn't be upset by nettles, they're important food pants for caterpillars
