Bring vibrant color and wildlife value to your garden with Great St. John's Wort (Hypericum ascyron), a striking native perennial shrub known for its large, golden-yellow blooms that appear in late summer. These stunning flowers provide a vital nectar source for pollinators, including native bees, butterflies, and moths, at a time when many other plants are beginning to fade.

As the seasons change, ornamental seed pods develop, providing food for birds and winter garden interest. Its strong, upright form and textured foliage make it an excellent addition to borders, native shrub plantings, and wildlife gardens.

Key Features:

• Brilliant Late-Season Blooms: Large, showy yellow flowers attract pollinators when other nectar sources are scarce.
• Wildlife-Friendly Seed Pods: Persistent seed capsules provide food for birds and add winter interest.
• Thrives in Sun & Part Shade: Adaptable to different light conditions, from full sun to part shade.
• Low-Maintenance & Drought-Tolerant: Once established, requires little watering and no synthetic chemicals.
• Deer-Resistant: Naturally unappealing to deer, making it a great choice for gardens prone to browsing.
• Pollinator-Safe: Grown non-GMO and free of harmful neonicotinoids, promoting a healthy ecosystem for pollinators and wildlife.

Available in sets of three, six, or 12 plants to suit gardens of any size. 

Planting Tips:

1. Location: Plant in full sun to part shade in moist, well-drained soil; tolerates occasional wet conditions.
2. Watering: Water regularly during the first season to establish roots; drought-tolerant once mature
3. Maintenance: Minimal care required. There's no need to deadhead the flowers, as allowing them to go to seed provides a valuable food source for birds. Leaving the stems standing in the fall offers overwintering sites for beneficial insects. If desired, cut back the stems in late spring after pollinators have emerged.
