Is this a weed?

Looks pretty, purple clover? Garden centres seem to sell it, so I would say no.

There's a simple method to find out if it's a weed
Pull it out and put it on the compost heap.
If it grows back it was a weed
If not it was a flower.

Its only a weed if you don't want it there :)

I think it's oxalis. Weeds are just native UK plants, if they're pretty and don't spread more than you want, they're not 'weeds'. Wildflowers are great for wildlife. I'm not sure how this particular pretty plant is categorised!

It is pretty and looks like clover leaves. I’m going to risk it and leave it!

I agree that it's oxalis, generally seen as a weed and can be a bit invasive. It spreads by seed and bulbils under the ground.

Yep, oxalis. It's pretty but invasive.

Oxalis that is the weed is tiny I think and spreads everywhere. This looks more like one that I bought from a garden centre which is not a weed and IME doesn't spread like a weed.

It is oxalis. A wildflower, low spreading with a pretty yellow flower. People buy these so not a weed.

Not a weed. Its a cultivated form of oxalis. I know cos I saw one on sale today in a garden centre, and quite expensive! It has lovely colour of folliage that will look great with other things in the garden.
Anyway, what is a weed?

That is the green one, but the leaves are beautiful and so are the flowers.
