This is the most common plant, of the limited number, one will find along the sea shore. It, like pea plants, is a runner. It grows above the tideline flourishing amongst the rounded stones and sand. Anyone familiar with the garden pea plant will immediately recognize the flower of the beach pea. Its flower is of a rather complicated arrangement and coloured pink-lavender; it is quite showy. And, yes, little pea pods will show up where the flowers have been.
It is thought that the herbage of the beach pea contains a poisonous alkaloid.
