Valerian (Valeriana officinalis, Caprifoliaceae) is a perennial flowering plant native to Europe and Asia.[1][2] In the summer when the mature plant may have a height of 1.5 metres (5 feet), it bears sweetly scented pink or white flowers that attract many fly species, especially hoverflies of the genus Eristalis.[3] It is consumed as food by the larvae of some Lepidoptera (butterfly and moth) species, including the grey pug.

Crude extract of valerian root may have sedative and anxiolytic effects, and is commonly sold in dietary supplement capsules to promote sleep, but clinical evidence that it is effective for this purpose is weak or inconclusive.[1][2] Its roots and leaves cause a catnip-like response in cats.
