St John's Wort

St. John's Wort

St John’s wort (Hypericum perforatum) is a perennial plant named after Saint John the Baptist. This is because the plant flowers around June 24th, the birth date of the saint.

This plant can be found natively in all four corners of the world. In agriculture, it is considered to be an invasive, noxious weed. This is because in the wild, it does conquer and replace native species, while also being quite toxic to livestock if ingested as a whole plant.

GROWING ST. JOHN’S WORT

Hypericum perforatum reproduces vegetatively and sexually. Its perennial nature provides growers with the benefit of multi-year harvests.

Seeds should be sown in autumn, as it is during winter that germination slowly takes place. It is an easy plant to grow; its major requirement is an alkaline soil profile, and it flourishes in very humid and cold weather. It can grow up to 1m high, and if left unmanaged, will form a wide, spherical bush shape.

Once in full bloom, you can harvest its yellow flowers and let them dry out completely for long-term storage.

Leaves: 20 grams

Seeds: 0,5 grams (about 4.500 seeds)
