Large-flowered Evening-primrose (Oenothera glazioviana)
Description:

Masses of these lovely Evening primroses, around 3 foot high with clusters of large flowers around 4-5cm across, with styles projecting beyond stamensm crinkly leaves, red stippled stems, were flowering in profusion on coastal sand dunes on the Gower peninsula, Wales. I know Oenanthe is a tricky genus, but these seem to fit O. glaziovana and I have found many records of it in Welsh dunes and one for Port Eynon specifically where this was taken. The hybrid O. fallax is similar but I think the flowers fit glaziovana better from what I've read.
