This plant is rapidly taking over, growing in the borders, cracks in paving and pots. Does anyone know what it is? I wondered if it was a form of campanula. It climbs and trails. The photo makes the flowers look blue but they are more purple.
Muddy, Looks a lot like Vinca Major or periwinkle a vigorous sub shrub the five petals and glossy leaves remind me of it but then I could be wrong.
It's a trailing campanula, we've got it growing everywhere we let it. If you pull it out it'll reappear next year.
Thanks for your responses. Having followed the link my flowers are more a purple colour but I do think it's very likely to be a campanula. I shall apply my usual containment methods. It's a shame it's got into the block paving as this is a real pain to keep looking tidy.
It's a Campanula Portenshlagina- I had the same problem- you have to dig out ALL the roots that go quite deep or it will just grow back again and smother everything. Make sure you get every last bit !!
Haven't tried the glyphosate on it so let me know if you have any luck with that. It spread all over my rockery and I had to basically take the whole thing apart and tediously pull each piece of root out, put the whole thing back together again and replant with new plants! I wish I had not planted it in the first place ! Ahh well- we live and learn !
Glyphosate will work!
Flamethrower might be my solution then. Thanks for everyone's help
