"desirable" plants that become invasive monsters

    Lily of the valley and vinca major, planted by previous owner and spread throughout the perennial border. In fact some still pop up several feet away from where they were first planted.

    2 more votes for Japanese anemone and crocosmia here. Slightly concerned re Lily of the Valley comments, have recently planted 4 clumps. When I rented out my house a few years back, the tenants planted Macleaya, I managed to get rid of it - what horrid bright orange roots it had. Oh and I still get the odd acanthus leaf poking through, but that's removed on sight. One advantage of having very dry light soil is that digging these thugs out is relatively easy, I would imagine it's a nightmare on anything heavier.

    Agree with Japanese anemone - the pink ones, anyway, Vinca major and Acanthus. Spanish bluebells are also a pest for me. Other people's thugs - Crocosmia, lily of the valley, that light green pleated leafy thing that looks pretty with water droplets on (can't bring name to mind) won't grow at all for me.

    Vincaimage alchimilla, borage which pops up every where once you have it, and crocosmia, but it is more esily controlled once you inderstand its habits!, And acanthus

    Most lists on here are very similar. Just bought 3 plants of Cornus midwinter fire - based on what Obelisxx says perhaps it's a mistake - they are not planted yet.image

    And Japanese bluebells, their thick leaves prevent anything growing, I spent years at the other house slowly eradicating them.image

    For some reason my Alchemilla Mollis behaves quite well in the actual soil but I am forever pulling it of the cracks in the path and patio.  I try to remember to cut the flowers off before the seeds set - I don't like the smell of the flowers so that helps!

    I have alchemilla too but am ruthless about cutting off the flowers to restrict its spread.  My flower arranging friend almost wept when she saw me doing that and chucking them on the compost.      i find it's a good weed suppressor whilst waiting for other more interesting plants to beef up.

    I have to BUY A. Mollis if I want it !! Maybe it's better that it doesn't like my garden image
