Please see photos, there are lots of bees buzzing around this plant on my allotment, photos aren't great unfortunately, but on the plant which is about a metre tall are little green balls, which turn into a small purple flower, which bees seem to love. In the first pic it is on the far left of the flower plot, and in the others , in the foreground. Just curious to know what it is. Thanks.

Sorry, I can't tell from the photos.

But people often report success either through using Google Lens on your smart phone, or an app like PlantNet.

Looks a bit like one of the Verbena family to me, maybe this one https://www.crocus.co.uk/plants/_/verbena-hastata-f-rosea/classid.2000006787/sku.RH30001512/?gclid=CjwKCAjw5remBhBiEiwAxL2M9_EG0tS2EjHI1oldkFbjANjBNk0_SvYrHSUoNmUjd-GJLW297gjGjRoCybwQAvD_BwE

I thought maybe Thalictrum, but hard to tell from the pictures.

The buds look right, but the foliage not so much

Thanks all, could be mumofstig's choice. I'll see if google lens comes up with anything as suggested, and let you know. Google Lens coming up with Figwort from the pics, I'll go down when its drier, and use the live camera function and see what that says.

I thought possibly "Mallow", but I may be looking at the wrong flower    Mrs Bouquet

PS: NO sorry was looking t the wrong one.  Please tell me what the plant is.

Tried the live camera option on Google Lens, came up with Figwort, every time, true I reckon, attractive to bees etc. Looked at a few pics on line, 90% sure.
