Summary

Hydrolea quadrivalvis, commonly known as waterpod, is a perennial herb that is native to wetland habitats such as swamps, marshes, and wet ditches in the southeastern United States. It is found in states like Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, and Virginia, and has been introduced to Maryland. The plant typically grows up to 24 inches tall and features lanceolate leaves that are 2-4 inches long. It is characterized by stout thorns on the nodes and distinctive sepals and stems with spreading, jointed hairs.

Waterpod is valued for its role in supporting wetland biodiversity and can be used in water gardens or naturalized wetland plantings. It prefers full sun to part shade and requires consistently moist to wet soil conditions. While it is not commonly used in traditional garden settings, its presence in a wetland garden can provide habitat for wildlife and contribute to water purification. Gardeners should be aware that this plant thrives in wet environments and may not be suitable for drier areas.CC BY-SA 4.0
