This is the smallest species of Bulrush in existance. The fine, grassy, linear, upright growing leaves (width 1-3 mm) are bluish-green. The inflorescenses on top of the flower-stems are composed of thick, almost ball-shaped, brown, female, dumpy flowers (2-5 cm tall) with the yellow male ones like a ‘tail’ on top. With all bulrushes the flowers are pollinated via wind. This species is endemic in all of the moderate clime-zones in Europe to far into Asia. Especially this species needs a lot of sun (shadow is less tolerated). It grows well in fertile soil in shallow water in pond-edges and marshes (in mini-ponds too). Dwarf Bulrushes are hardly or non-invasive. Good winter-hardy.
