St. John's Wort
In order to avoid having the flowers picked it was believed that this plant could move about! Hanging bunches of these flowers though once caught would ward off evil spirits if placed above a door. It is a golden flower and was the emblem of the sun god in pagan times (particularly at Midsummer). Originally known as the 'sun god's flower' the Christians dedicated Midsummer to St. John the Baptist and renamed the plant St. John's Wort.
