White cottonsedge is a striking arctic and alpine perennial grown for its fluffy white cotton-like seed heads that emerge in spring and summer. It requires consistently wet, acidic, boggy soil and full sun to partial shade, making it ideal for pond margins, rain gardens, or peat bog features. This is a specialist plant best suited to gardeners recreating moorland or wetland habitats.
