Such a pretty little flower - bought some seeds from my parent's garden in Wales __ must be over 50 years ago and now they self seed at will in my back garden - so cheerful and bright in small clumps here and there ! This little herb has medical purposes and is believe if a few of the leaves are chewed that the would relieve migraine headaches ! I used to try it in my early 20s I am not sure if it worked or not , but I quite liked chewing on the bitter tasting leaf !! fav
