Triadenum virginicum

Marsh St Johns wort

 

Marsh St. John’s wort is a wetland perennial that brings soft structure and subtle color to saturated soils, pond edges, and rain gardens. Its upright stems are topped with starry pink flowers in midsummer, and it thrives where soils remain consistently moist to wet. This species is especially valuable for filling the often-overlooked niche between emergent wetland plants and upland perennials.

 

The flowers attract a range of native bees, including sweat bees and bumble bees, as well as small butterflies. Its dense growth provides cover for amphibians and wetland insects, and the plant contributes to overall habitat complexity in wet sites. This Triadenum is an excellent choice for gardeners and restoration projects focused on functional wetland ecosystems.
