Eriocaulon compressum, commonly known as Flattened Pipewort or Compressed Button Snakeroot, is a perennial herb native to the southeastern United States, particularly thriving in wet savannas, seepage bogs, and along the edges of ponds and streams. It typically grows to a height of 0.5-1 feet (0.15-0.3 meters) and forms a basal rosette of narrow, grass-like leaves. The plant produces small, spherical, white flower heads that bloom in the summer and are held above the foliage on slender stalks. These flowers are not particularly showy but are interesting upon close inspection.

Flattened Pipewort is valued for its ability to thrive in wetland conditions, making it a suitable choice for water gardens, rain gardens, and naturalized areas where it can help stabilize soil and provide habitat for aquatic wildlife. It requires consistent moisture and does best in full sun to part shade. It prefers very slow draining loam or clay soils that are high in organic matter. While it is not commonly found in the nursery trade, it can be a unique addition to a native plant collection or for those looking to support local ecosystems. Care should be taken to ensure that it is not planted in areas where it could become invasive outside its native range.CC BY-SA 4.0
