P. WF. Ancient herb growing to about 3ft high, with hollow stems and clusters of small, tubular pink or white flowers. Smells of vanilla. Flowers June to July.
Attracts bees and moths (Valerian Pug moth and Lesser Cream Wave). Apparently cats find it asa attractive as they do Catmint! Dried root can be used as a moth repellant. Has been used since antiquity to treat sleep disorders and nervousness. Makes a good companion plant for vegetables.
