Difficult to tell but the leaves do look like perennial geranium . Has it flowered at all?

Thanks Anchorman.

I've never noticed any flowers. The stems are very tough.

My partner believes it is something called 'welsh buttercup' but I don't know.

Could be the leaves do look a bit big for a geranium

Could well be creeping buttercup.

Thanks Owdboggy.

Would you consider that to be a weed?

I think Hardy Geranium and and not Creeping Buttercup. Creeping Buttercup is a weed that you do want out of your garden as it, erm creeps, all over the place. I am forever taking it out of the borders. Hardy Geranium is good to have as it grows well, looks good and normally pest free. It flowers in spring.

Hello everyone.

Thinking of it the plant does flower-usually a purple colour.

It is a perennial geranium so not a weed. why not lift it in the spring and plant where you can enjoy it.

I think Geraniums are weeds as much as Buttercups, but if it has purple flowers then a Geranium it is.

Yes, it's definitely a hardy Geranium. I'd leave it unless you want to use the ground for something else. It has obviously decided that it's happy in that space!

I've got some of this Geranium, the colour is blue on mine, they look lovely but need a little controlling and when the flowering is nearly over I cut it all down and get a second flowering, I'm thinking of digging some of mine up and putting them all along my driveway :o)
