Nuisance wildflowers etc

Are there any wildflowers or liberal self-seeders that you wish you hadn't encouraged? I wouldn't be without the ones on the list but I wish I'd been a bit less welcoming. They are becoming a real nuisance.
Verbena Bonarensis
Scarlet Pimpernel
Valerian. ( white and pink. Red isn't a nuisance - yet)
Nigella
Pulmonaria
Celandine
Aquilegia
Fennel

    For me out of control (and not necessarily encouraged, but I think they still fit the bill) are

    Purple toadflax (Linaria purpurea)
    Skullcap (Scutellaria columnae) very pretty, it's a pity, did encourage it one time.
    Viola odorata - rampantly self-seeds
    Comfrey (Symphytum officinale) I have a few plants that I prevent from going to seed
    Balm mint (Melissa officinalis)

    I am also interested in the list you've been happy to have encouraged! Can we additionally have a list of 'Gentle self-seeders/spreaders, possible to control'? To me that's, so far,

    Fumitory (Fumaria muralis)
    Digitalis (species Foxglove)
    Evening primrose (Oenothera stricta)
    Yellow Corydalis (Corydalis lutea)
    Teasel (Dispacus fullonum)
    Californian poppy (Eschscholzia californica)
    Ground ivy (Glechoma hederacea)
    Ivy-leaved toadflax (Cymbalaria muralis)
    Vicia sativa (Such pretty flowers, but needs firm control)

    I'm still waiting to pass verdict on

    Common agrimonyl (Agrimonia eupatoria)
    Herb robert (Geranium robertianum) it seems easy to control so far

    Valerian officianalis (a perennial) is a PITA but I do love it. I have to spend most of the year digging it out. If I can find a less vigorous umbelifer I will probably swap over.

    Ox eyes were a bit much but not hard to spot and dig out when small. They seed in the patio, in all the pots, everywhere.

    Celendine was here when I moved in and there's bugger all I can do about it. I let it be.

    Medick I'm not sure about it. It's in a new plot and I'm yet to find out how much of a take over thug it will be. It seems find around the edges.

    Most of your list @B3 I would love to self seed and hasn't. I'm waiting for erigeron to spread (after about six years). Fennel and foxgloves would be great but the slugs take all. I suspect that is why few things seem to get going from self seeding in my garden, like erigeon. They probably do seed but get eaten straight off. ( 💡A light bulb moment - thanks for that.)

    I forgot to add wild marjoram. It's untidy and a spreader. I usually put up with it for the butterflies but so far, they haven't come to the party.

    Teasel rarely seeds in a good place. Right in the middle of a path is a favoured option.

    yes - why does it do that?

    It also lurks at the front of the border pretending to be a primrose. But I'm wise to it😡

    They keep turning up in the middle of the drive. Honesty is another of the 'possible to control' ones for me. And ferns. Polypody and hart's tongue and another, tiny one that I've not identified yet

    I'd dearly love some self seeded hesperis, lunaria and foxgloves. I suspect I might need to move house for that.

    Another one I'm still gauging is Salvia forsskaolii, it is quite the enthousiastic self-seeder, both in the garden and in the patio cracks. I love its flowers, here (lilac-coloured I would say) with Erigeron:

    I lost my temper with some of the soggy and flattened annual poppies yesterday and ripped some of them out. I've also tied string around the pretty ones so I only let a few plants seed instead of 50,000.

    I also ripped out some of the blotchy old garlic mustard plants that I kept too many of this spring, but then I found a chrysalis stuck on one so I guiltily piled it back in the border :/.

    There's a path that goes through this borage field but I haven't the heart to smash through it.  Plus borage is pretty tough and I'd probably come off worse.
