How to get rid of Lesser Celandine

We have had the same garden for nearly six years and last year Lesser Celandine raised its pretty but destructive head. I have never come across it before in 40 years of gardening, I’ve been digging it out and using Thrust weed killer, so far without major success. Has anyone got a better cure for this pest which is killing plants, I also don’t like using chemicals in the garden.

    What is it killing?
    Last year something ate all the leaves off mine but left the flowers. It's back in force this year but I've never known it to kill anything.

    Sorry, but lesser celandine is not killing your other plants.   It has a very short period of high activity in spring with flowers that provide essential food to bees and other beneficial insects when few other sources of pollen and nectar are available.  It then dies down till the following spring, ceding its place to other plants.

    If other plants are failing I expect it's more to do with cultivation than this plant so check your soil for drainage and fertillity.  Is it heavy/stagnant/poorly drained/lacking nutrients?

    Digging it out can actually help spread the teeny bulbils and chemicals are best avoided because they have side effects and unintended consequences for other plants and critters.

    I have dug out loads, but it always comes back. I haven't found that it kills plants, especially if I thin it out. It completely disappears in summer.

    It's only there for a short time, and other plants will easily cover it as it dies back through summer. I love it, and often wish I actually had it in the garden, as I love seeing it at this time of year, and would be great in the shady bits to follow the snowdrops, and grow alongside the primulas and lily of the valley to give a succession.  It's still nice just now round here, in the areas with large deciduous trees, especially on sunny days when it opens properly. 
    It's not killing your plants, as others have said. Something else is causing that, and there could be many reasons.  :)

    It's a losing battle.  A brief truce is the best you will get.  It's really quite a gay flower, I live with it.  Shade helps to control it, and stops the flowers looking quite so brassy.

    Lots of 'Brazen Hussey ' for sale at the local GC no one buying it half price but no takers.
    Not for a small/ medium garden. Belongs in a meadow.
    I do have a collection of doubles , sterile seed, spreads by bulbils , not the same problem as the singles. There are dark leaved doubles with orange flowers. 
    B3 I have seen pheasants eat the leaves and pigeons may like them as well.

    I don’t understand why we love primroses but try to get rid of the cheery little celandines. Primroses can spread exponentially if the conditions suit them, and while celandine leaves disappear quickly after flowering, the leaves of primroses grow quite large and take up more space. 😵‍💫

    I understand:  Brazen Hussy says it all .  Brassy yellow flowers, even worse with red-shade leaves..  TYpical Christopher Lloyd "shock of the new".  

    Wild primroses are a delicate virginal pale yellow.  And primroses are easy to transplant (and lose).

    Brazen Hussey 🤣🤣. That's a new one on me and now I'm going to have "Don't look Ethel" in my head all day. Under 50's probably won't get that reference. 🤣

    Primulas grow so well here, and flower on and off all year, and I wouldn't be without them, but they do have their problems. Mostly tatty foliage from the slug damage.
    The celandines are terrific in that sense @Dovefromabove - no mess!
