They could be Chives where the flowers have gone to seed.

Certainly an Allium of sorts.

Chives for sure I reckon... pull a stem or two, it should taste oniony - the flowers are edible too, though I wouldn't fancy eating these ones, as they're well past fresh...

thanks all, is it OK to chop them down if there finished then

Yes, then you will get a nice new crop of fresh leaves to use in cooking.

Looks a bit like Armeria maritime to me? I have it growing round my pond.

Armeria are evergreen perennials forming tufts or mats of strap-shaped or linear leaves, with long-stalked, dense clusters of small cup-shaped flowers

Details
A. maritima is a mat-forming evergreen perennial with dense, needle-like leaves and erect scapes to 15cm, bearing compact clusters of cup-shaped pink flowers in late spring and summer.

If it is, its Drought Resistant too :o))

Armeria has shorter, more grass like clumps of leaves, but if those flowers were lilac coloured, that would confirm chives.

Mmmm! The leaves on my Armeria are quite long, I will add a picture to my Pics for you to see, Ive looked at the seed heads & they both look the same on chives & armeria? so quite confusing LOL but you are most probably right Bamboo, you will see in my pics why I'm confused LOL.

If you enlarge the image you can see the black seeds in the centre of the flowers. Armeria has a grass-like awn for a seed.

LadyEssex1: If you compare your photo of Armeria and the chives above, you will see that the leaves on the Armeria are shorter and tend to grow all over the place, like a knot of grass - the chive leaves are slightly broader/rounder, and more inclined to stand upright. Armeria leaves also tend to have a rib or vein running from top to bottom, which is also not a feature of Chives. The curly stems on the spent flowers on yours are never seen on chives either, only on Armeria (though not always). Chive flowers tend to remain upright, because their stems become quite stiff as the flowers fade.

when i chopped them down there were millions of little black seeds falling all over the place, and the heads were purple, confirmed by the owner, so i hope we have all steeled on chives, the had an onion smell also.

thanks for all your help in my little problem

Glad my Question Mark is solved, Chives it is LOL xx
