Hypericum denticulatum, commonly known as Coppery St. John’s Wort, is a perennial herb native to wet meadows, pine barrens, and prairies in the southeastern United States. It can be found at elevations up to 1312 feet. This species typically features erect stems that can reach up to 3 feet in height and bears coppery yellow flowers with prominent stamens that bloom from May to June, attracting a variety of pollinators. The ovate leaves add to its ornamental value. The plant’s flowers are not particularly showy but do provide a subtle charm to naturalistic plantings.

Coppery St. John’s Wort is valued for its adaptability to wet conditions and is often used in rain gardens, native plant gardens, and for naturalizing in moist areas. It thrives in full sun to part shade and prefers moist to wet soil with good drainage. While it is relatively low-maintenance, it can be susceptible to rust and leaf spot diseases. Gardeners should be aware that, although not aggressive, it can self-seed in optimal growing conditions. This plant is not known for its invasiveness but should be monitored to ensure it does not spread beyond desired areas.CC BY-SA 4.0
