FAMILY SCIENTIFIC NAME
Valeriana officinalis is an herbaceous perennial that grows 0.5-1.5 m (1.5-4 ft.) tall. The plant grows from a small rhizome and has fibrous roots. The stems of this plant are generally pubescent, especially at the nodes. Both the basal and the stem leaves are oppositely arranged and are similar in appearance. They are both pinnately divided into 11-21 lanceolate segments that have dentate margins (some are entire). As the leaves go up the stems, the petioles get shorter. The leaves often have a few hairs on their underside. The fragrant flowers of Valeriana officinalis are white or pale pink and are borne in many umbel-like inflorescences. The individual flowers measure 4 mm (0.2 in.) long. There are pectinate scales that can be seen with a 10x hand lens on the lobes of the calyx . The bracts of the flowers are linear-lanceolate in shape. Flowers are present on the plant from June to August. The fruit are small and lanceolate-oblong in shape, measuring 3-5 mm (0.1-0.2 in.) long.

Valeriana officinalis has wind-dispersed seeds. It can also reproduce locally by means of aerial stolons.
This plant is native to most of Europe, as well as parts of west Asia, Japan, Korea and China. In the United States it has been found from Maine south to West Virginia and west to Minnesota and Iowa. In the western part of the country it has been found in Washington, Oregon and Idaho. In New England, this plant has been reported from all states except Rhode Island.
HISTORY OF INTRODUCTION IN NEW ENGLAND
Valeriana officinalis has been present in the United States for at least 150 years. It was likely introduced even earlier than this because of its use as a garden and medicinal plant.

This plant can grow in a variety of different habitats ranging from grasslands to wooded areas. It can tolerate both dry and moist soils. It is often abundant near the coast.
Valeriana officinalis is still cultivated today for its medicinal use. Due to its multiple introductions, it has frequently escaped into the natural landscape where it can displace native plant species.
Documentation required: A specific photograph or mounted snippet of a portion of the stem with an inflorescence.
