These pictures show Red Valerian (Centranthus ruber) – which actually has dense terminal spikes of deep pink (not red) flowers that can also be white – growing on the dunes at Swansea Bay. It is an introduced species that has naturalised and is not the same as our native Common Valerian (Valeriana officinalis) which has very much paler pink flowers and not so much branching of the stems.

I love this plant is it incorrect to call it by a common name of bouncing bess. I have enjoyed seeing its bright blooms growing on walls and banks in France and Spain. So resilient. Now I see on the beach too. Lovely pictures as usual.

I have never heard of Valerian being called Bouncing Bess but I like it. Maybe it is a name used locally to where you live?
