Cirsium Heterophyllum out of control

I'm not sure what I should do about my CH - I got it last year and it didn't do a lot, but this year it's back with a vengeance!  You can see it popping up all over the place - see right to the right of the pic it's sneaking up next to an echinacea.  Is it going to stop other things growing?  I don't know whether to just leave it be or get involved somehow??  Any help gratefully received.

     I wouldn't be too concerned. It is obviously happy with the growing conditions!  Perhaps remove and pot up the ones in the way of other plants, perhaps gift them or sell them? I can't even grow them lucky you.

    Thanks - I didn't know if there would be some massive root system underneath that I can't break through. I guess I can try digging around one and see what happens.

    @Crazybeelady I would assume it has a tap root so shouldn't be a problem. All gardens have plants that can be enthusiastic but with some editing they make a garden look natural.

    I have cirsium rivulare in several spots, while this does not self seed it has become a substantial plant with a spread of 3/4 of a Mt. Have just split it to spread it around. The RHS website mentions self seeding can be a problem with your variety

    I'll bear that in mind @Wilderbeast, it only gave me one flower last year so it wasn't an issue, dont think that'll be the case this year!

    @Crazybeelady I grow just one thistle Galactites Tomentosa it is invasive in countries like Greece. I had one plant ten years ago, some years I can have one or two seedlings, one year I thought I had lost it altogether. Other years there have been fifty plus. They have never been a  problem to deal with and fill gaps in the winter border. I have found that potting them up is not always successful, possibly because of the tap root.

    One last thought you could dead head some and say leave one plant for seed? The year I thought I had lost my G tomentosa they turned up in my neighbours garden. They remind me of snow flakes against bare soil but as said they will seed if happy.

    I think I'll sit back and watch exactly what it does this year and then tackle accordingly!
