Hypericum perforatum 'Common'
St. John's Wort
Native to Europe, western Asia and northern Africa. Plants were first brought to North America by settlers in 1696, and have naturalized over time throughout much of the continent. Since ancient times, plants have been used as treatments for a variety of medical problems, including externally for wounds, inflammations, burns, skin disorders, and nerve pain, and internally for anxiety, depression and insomnia. The flowers were at one point gathered and displayed to ward off evil spirits. Flowers are typically in bloom on the birthday of St. John the Baptist (June 24), hence its common name. Zone 4-8.
