I am stumped. Without a photo of leaves, as opposed to the bracts under the flower clusters in your photos, and a photo of a whole plant, I cannot ID this plant. Betty

BettyDonWood MichaelMulvaney - thanks, the 4 petal versions of the common centaury were found in close proximity to 5 petal versions (the 4 petal versions making up 20% of the number). They were quite distinct: smaller, carrying fewer flowers, with ragged basal leaves.

I am loath to sugest Centaurium erythraea, which in my previous experience always has 5 petals, but there is nothing else I know even vaguely like it.

A few of our other sightings have what look like 4 petal flowers amongst predominately five petaled one
