Alpine bulrush (Trichophorum alpinum) is a small, leafless-looking sedge from cold northern regions, found in bogs and mountain meadows. It is a wild plant rather than a common garden subject, so it is grown mainly in bog or native gardens where cool, wet, acidic to lime-rich conditions can be matched.
