St John’s Wort, or Hypericum, is a sunny, golden-yellow flower known for its medicinal properties, radiant blooms, and symbolic association with light and healing. Its name derives from St John the Baptist, whose feast day falls near the summer solstice—when the plant is traditionally in full bloom. Native to Europe and Asia, this low-maintenance perennial is commonly used in herbal medicine, garden beds, and floral design (especially its berries). It symbolises protection, courage, hope, and resilience.

St. John’s Wort is known for its mood-lifting and calming properties. It’s commonly used to treat mild to moderate depression, anxiety, and nervous restlessness. The active compounds (like hypericin) influence neurotransmitters in the brain. However, it can interact with medications, so consult a doctor before using it regularly.
St. John’s Wort grows in sunny, dry, and nutrient-poor soils, often found on meadows, roadsides, embankments, and hillsides across Europe. It prefers full sun and can thrive in gardens with poor soil, making it ideal for wildflower meadows.
St. John’s Wort is a bushy, upright herb about 30–80 cm tall. It has small, oval green leaves that appear dotted when held to the light (tiny oil glands). The bright yellow flowers, with five petals and many stamens, bloom in clusters from June to August.
