Wildflowers - St. John’s Wort

St. John’s Wort (Hypericum perforatum) is a perennial herb that grows up to 32 inches tall and is found in many parts of the world (including the Joyce Road neighborhood). The yellow flowers appear from June to September.

St. John’s Wort is a medicinal herb with antidepressant and anti-inflammatory properties, but commonly reported adverse effects include gastrointestinal symptoms (nausea, abdominal pain, loss of appetite, and diarrhea), dizziness, confusion, fatigue, sedation, dry mouth, restlessness, and headache.



St. John’s Wort gets its name from the tradition of harvesting it on St. John’s Day (June 24).
