Its most likely Malope trifida, an annual plant in the UK, but for ID purposes, its important to be able to see the foliage as well

It might also be Malva sylvestris mauritanica, but a good look at the leaves would help settle the question, Tommy.

Hi, sorry Bamboo and Tug, but my first thought was Salpiglossis, but these days I seem to be getting a few wrong id's, Derek.

To be fair, without sight of the rest of the plant, its hard to say for sure what it is!

Hi Bamboo, yes it would help make it easier to id, still no guarantee of getting it right though, lol, Derek.

Just read your profile Tommy - goodness what a chapter of accidents! I hope you are doing better these days!
