Common valerian

About

Valeriana officinalis grows where the soil is moist: in marshy meadows, on the banks of streams and rivers, in wet thickets, at forest edges, and in clearings. In the Carpathians, it can be found from the valleys to the mountain forest zone, often alongside meadowsweet and other tall herbs.

This perennial plant is 50–150 cm tall with a straight hollow ribbed stem. The leaves are pinnate, with 7–11 or more elongated leaflets, arranged oppositely. The flowers are small, pinkish or white, gathered in large umbrella-like inflorescences at the top and have a sweetish smell. The rhizome is short, with numerous thin roots that have a characteristic sharp smell, especially after drying.

Valeriana blooms from June to August. Traditionally, the rhizome with roots is harvested in the fall. The smell of the roots is very attractive to cats, hence the folk name 'cat's root.'

Valeriana with large white inflorescences in wet places should be carefully distinguished from poisonous umbellifers that grow in the same habitats, particularly from water hemlock (Cicuta virosa). In umbellifers, the inflorescence is a compound umbrella on 'spokes,' and the leaves are several times dissected. In valeriana, the leaves are simply pinnate, with elongated serrated leaflets, and the inflorescence is an umbrella. If in doubt, do not dig it up.

Where in the Carpathians

The map shows where naturalists recorded the species (GBIF, CC0 and CC BY records), not every place it lives. The Ukrainian Carpathians are less studied, so a blank area does not mean the species is absent.

When to see it

From naturalists’ observations in the Carpathians (iNaturalist, research grade): the darker the cell, the more often the species is seen that month.

Safety

Do not confuse with poisonous umbellifers in wet places (water hemlock, poison hemlock). According to EMA, valerian products may reduce attention — do not drive after use; consult a doctor.

Look-alikes — how to tell them apart

In folk tradition
