Summary
Hypericum tetrapetalum, commonly known as Fourpetal St. Johnswort, is an evergreen subshrub or shrub native to wet flatwoods, pond edges, and marshes in the Southeastern United States, particularly Florida, and not native to Cuba. It typically grows 20–100 cm (7.9–39.4 in) tall and is characterized by its woody base and upright form. The plant produces terminal flowerheads with one to three flowers, each boasting 4 bright yellow petals, about 20–30 mm (0.79–1.18 in) in diameter, and numerous stamens, creating a showy display. Flowering occurs throughout most of the year, peaking in the summer months.
Fourpetal St. Johnswort is valued for its extended flowering period and vibrant yellow flowers, which can add a splash of color to garden settings. It is suitable for naturalistic plantings in wet areas, such as rain gardens or near water features. This species prefers full sun but can tolerate partial shade, and it requires medium amounts of water with soil that provides slow to medium drainage. While generally low-maintenance, it can be susceptible to root rot if drainage is poor.CC BY-SA 4.0
