The Story
Plant Bio
Eriocaulon decangulare, commonly known as Ten-angled Pipewort, is a perennial aquatic or wetland plant distinguished by its basal rosette of narrow, grass-like leaves and unique, button-like white flower heads on long, ten-angled stalks.
This species is notable for its long, twisted flower stalks (scapes) which have ten distinct angles. The white, button-like flower heads resemble old-fashioned hatpins, giving it a unique appearance in wet meadows, bogs, and pond margins.
