Pendulous Sedge Seeds carex pendula – grows on heavy damp soils often in damp woodlands and alongside streams. Because of its attractive foliage and flowers, pendulous sedge is often used as a garden plant where it can be grown at the edge of a pond or in any area of damp shade. Plants often form dense clumps and can grow to about 1.5 metres tall. Pendulous Sedge produces attractive yellow-brown flower spikes that resemble catkins. These are very attractive and appear mainly in May and June. Pendulous Sedge looks best growing with other wetland plants that flower in early summer such as Ragged Robin, Yellow Flag iris, Globeflowers and Snake’s head fritillaries.
