Summary

Hypericum punctatum, commonly known as Spotted St. John’s Wort, is a perennial herb that is native to open woodlands, meadows, and grassy roadside areas across eastern North America, including the eastern United States and southern Canada. This species typically grows to a height of 50–100 cm (20–39 in) and is characterized by its erect stems and dotted leaves. The bright yellow flowers, which bloom from July to August, are 2.5 cm (1 in) in diameter with black dots along the margins and are quite showy, attracting pollinators. The fruits are small, dry capsules that ripen from early September to October.

Spotted St. John’s Wort is valued for its medicinal properties, as well as its ornamental appeal due to its cheerful flowers and its ability to attract a variety of bees, including the American bumblebee and sweat bees. It is commonly used in naturalistic plantings, wildflower gardens, and as a component in pollinator-friendly landscapes. This herb thrives in full sun to part shade and prefers soils with medium moisture and good drainage. While generally easy to maintain, it can be susceptible to rust and leaf spot diseases. It is not known to be invasive and does not have aggressive roots, making it a safe choice for most garden settings.CC BY-SA 4.0
