St. John's Wort
St. John's wort is a perennial medicinal and ornamental plant appreciated for its bright yellow flowers, which bring a beautiful sunny touch to flowerbeds, herb gardens, naturalized borders, and rustic landscapes. Its green foliage, flexible habit, and star-shaped flowers create a very decorative natural effect, while attracting pollinators to the garden. Easy to integrate into sunny areas, it is well suited for meadow-style gardens, rockeries, and areas where a robust and characterful plant is desired.
Easy to grow, St. John's wort prefers a location in full sun or partial shade, in well-drained, light to moderately fertile soil. Once established, it tolerates drier conditions quite well and requires little maintenance, making it an excellent plant for sustainable gardens and low-maintenance landscapes. Light pruning after flowering or at the beginning of the season can help maintain a more compact, well-branched, and more floriferous plant.
Traditionally recognized as a medicinal plant, St. John's wort is mainly cultivated for its botanical interest, its vibrant flowering, and its ability to attract biodiversity. Its yellow flowers combine very well with grasses, yarrows, salvias, coneflowers, lavenders, and other sun-loving perennials. It is an ideal plant to add color, texture, and a natural touch to a medicinal garden, a flowering border, or a sunny landscape.
