Red valerian was introduced in the 1600s from Europe, but is now naturalised in the UK. Its pinky-red flowers grow from old walls, roadside verges, railway cuttings and cliffs, and provide nectar for insects.

Habitats

Ynghylch

The dense clusters of deep pink, almost crimson flowers, of red valerian are unmistakeable as they grow out on tall stems from old stone walls, roadside verges, railway cuttings, cliffs and rocks. Introduced into gardens before the 1600s, this plant from the Mediterranean soon escaped and became naturalised in the wild. Despite its non-native status, it is a good source of nectar from May to October for bees, butterflies and moths like the Hummingbird hawk-moth.

Red valerian is an ideal garden plant, flowering for a long period and attracting all kinds of insects. It likes well-drained soils and can grow on walls and rocks; it self-seeds easily and can look very pretty when left to naturalise in wilder areas of the garden.
