5 Seeds Hypericum calycinum (St John's Wort) Evergreen Groundcover

This package contains 5 seeds of Hypericum calycinum, commonly known as St John's Wort or Aaron's Beard. This vigorous, low-growing evergreen groundcover features attractive, deep green foliage that forms a dense, weed-suppressing mat. From early summer to autumn, it produces a profusion of cheerful, bright yellow flowers with prominent central stamens, adding long-lasting ornamental appeal to shaded or partially shaded areas of the landscape.
This versatile plant is ideal for covering slopes, banks, and difficult areas under trees where grass struggles to grow. It also works beautifully as an edging plant, in borders, or as a living mulch around shrubs. Once established, this hardy groundcover spreads steadily by underground runners to fill in empty spaces with minimal maintenance. It can be used ornamentally for its colorful blooms and textured foliage, making it a practical and attractive choice for adding year-round interest to your garden.
