Valerian

Valeriana Officinalis

A perennial herbaceous plant that grows to approximately 1m (3ft) in height. The stems are hollow and hairy at the base and branch out towards the top. Dark green leaves grow in four to eight pairs on each stem (simple, pinnately lobbed and opposite with hairy leaf veins on the under side). The flowers are white, lavender or pink with three stamen. The fruit is one seeded with rhizomes (ovid, cylindrical and light grey/brown in colour and smell like dirty socks when dried), roots (when fresh taste sweet, spicy and bitter) and with occasional stolons. These are gnarled and light grey/brown in colour. The rootlets have hollow centres.

First recorded in 1st century AD under the name of Phu which reflects its unpleasent smell.
