Common St. John's-wort (Hypericum perforatum) is a perennial plant known for its profusion of bright yellow, star-shaped flowers with prominent stamens that bloom from June to August. The plant’s name comes from the tiny translucent glands on its leaves, which appear as small perforations when held up to light. Common St. John's-wort thrives in well-drained, sunny locations but also tolerates partial shade, making it versatile for various garden settings. Its compact form and vibrant flowers add both colour and texture to naturalistic landscapes.

Medicinal and Culinary Uses
Common St. John's-wort has a long history of medicinal use, particularly for its positive effects on the nervous system. It is known to be antidepressant, astringent, analgesic, antiviral, and anti-inflammatory. Typically taken as an infusion or tincture, it is used to treat mild anxiety, mild depression, and sleep issues. Externally, it helps soothe inflammation, burns, and minor cuts due to its healing properties. Note: Common St. John's-wort may interact with certain medications, so it is recommended to consult a healthcare professional before use.

Ecological Roles
This plant attracts various pollinators, especially bees and butterflies, drawn to its abundant bright yellow flowers. Beyond supporting pollinators, common St. John's-wort contributes to biodiversity in naturalistic gardens and can help stabilize lighter soils due to its adaptability to well-drained conditions. By cultivating it in gardens, one benefits from its medicinal and ornamental qualities while also supporting local ecosystems.

Growing Notes | Seeds - St. John's Wort

To germinate, common St. John's wort seeds require light.

Sprinkle the seeds on the soil surface, pressing them lightly to ensure contact, and keep the soil moist during germination, which should take 5 to 10 days. Ideally, use a very light-textured potting mix. If needed, you can add perlite to improve drainage. Transplant or thin seedlings 45 cm apart in well-drained soil.

In the first year, the plant remains relatively low and almost creeping. Starting in the second year, it will produce multiple upright stems that bear flowers around mid-summer.
