You can also see the red (pink?) Valerian poking its head into the picture. They are said to attract rats and cats. Apparently its the Actinidine in the oil of the flowers that attract the rats and cats. It's traditionally a seaside plant and it self seeds every where. The one in the pictures is growing from a crack in the mortar in the paving. The other flower is a fragrant geranium. I think its called geranium mandaresa? No doubt you will tell me.
