Habitat:

Originating around the Mediterranean, it is believed to have been introduced from Mainland Europe in the 17th century, it is now widely naturalised in the UK and many other parts of the world. As it thrives in warm, dry conditions it is more common in the South than the far North of the UK. It is often planted in gardens but can tolerate poor, alkaline rocky and sandy soil so can be found in a broad range of habitats, including in disturbed soil such as urban wasteland and in exposed sandy conditions on the coast. As it can tolerate alkaline mortar and cement, it is often seen growing out of old walls. 


Description:

Red Valerian is a PERENNIAL herb growing in dense upright clusters to 0.9 m (3ft) by 1 m (3ft 3in). It can appear more like a plant or a shrub depending on conditions 


Identifying Features of Red Valerian :

Leaves

The smooth, mid-green leaves are long oval shaped, starting out in rosettes in spring and then growing in opposite pairs on the stems as they emerge and grow tall. The lower ones can have a short petiole or stalk, while the upper leaves tend to attach straight on to the main stem.

Flowers

The flowers grow from June to October in large showy clusters at the top of the stem. They are most often a deep reddish pink, but can also be red,  paler pink, lilac or white. The individual flowers are very small, around 2mm across. Each flower has 5 fused petals joining a tube or spur on the back, arranged unevenly. The flowers are attractive to many kinds of insects and attract various species of butterflies and bees – though the strong smell is not so attractive to humans, sometimes being described as sweaty.

Potential lookalikes

As previously mentioned, this can be confused with True Valerian, which usually has paler pink to white flowers and pinnate leaves. Unlike red valerian, the pale flowers of True Valerian have a less prominent spur on the back of the flower, rounder petals and three anthers visibly poking out. You could also confide this with Yarrow, which has very feathery leaves and a textured ‘middle’ to the flower.
