At up to 1.2m it is slightly shorter than Common Valerian which reaches as high as 2m.

Likes damp ground, but is never actually in the water unless a flood occurs.

Flowers (which are in dense compound cymes - resembling umbels) are more pink than Common Valerian, even after opening (but most here are still closed).

Un-like Common Valerian the leaves are ovate to cordate and some are sub-orbicular (flat and elliptical). They are dentately (concavely) toothed.

The upper stem leaves usually have one or two smaller lateral leaflets, similar in profile to the other leaves.

Leaves here are cordate.

Some leaves have one or two pairs of opposite lateral leaflets nearer the main stem.

Just below the flower umbel are an opposite pair of much narrower leaves, which may or may not have one or two pairs of smaller side-lobes at right-angles to the leaf axis and nearer the main stem. This one doesn't.


Some similarities to : Hemp Agrimony (Eupatorium cannabinum) but that has longer narrower leaves similar to those of Hemp (Cannabis sativa).

Uniquely identifiable characteristics

Distinguishing Feature : Similar to Common Valerian (Valeriana officinalis) but with pink flowers and large cordate to elliptical leaves which are heavily and dentately toothed, the upper stem leaves often having one or two pairs of smaller but similarly shaped lateral leaflets.

Native to the Pyrenees and non-native to the UK, they were introduced and now naturalised in damp woods and shady hedgebanks in the south of Scotland and very scattered elsewhere.
