Latin Name: Hypericum perforatum L
Plant Description: St. John’s Wort (Hypericum perforatum) is a shrubby perennial plant with numerous bright yellow flowers. The term wort is an old English term for plant. Its naming after St. John was based on the claim that red spots, symbolic of the blood of St. John, appeared on the leaves of the plant on the anniversary of the saint’s beheading. St. John’s wort is cultivated worldwide, but grows quite well in Northern California and Southern Oregon.
