This plant is native to temperate aereas of Europe and Asia and also known as Greek valerian. It is apparently quite rare in the UK, where it is said to be growing at several locations on limestone cliff ledges in Yorkshire and localised places in Derbyshire. It used to be the only known member of its family until taxonimists decided to add a few more genera, currently including phox. The black dye produced by boiling the plant in olive oil is used for colouring grey hair. See > http://www.geograph.org.uk/photo/5405720 for a more detailed look of the flowers.
