Red Valerian can actually be pink, red or white, and the small flowers appear in numerous clusters on the plant. The plant is fairly tall and can grow up to nearly 80cm high.
It flowers May to October, and it is often found naturalised on the coast on cliffs faces, rocks, and on sandy and shingle beaches. It is also found on railways embankments, old walls and buildings, waste ground, parks and gardens. It was introduced from the Mediterranean in the late 1500s as a garden plant, and has now become naturalised. It is very common in the south of Britain, rarer the further north you go.
