About
Carex acutiformis, the lesser pond sedge, is a vigorous, clump-forming, spreading native sedge of ponds, streams and boggy areas, forming dense clumps of pale, greyish-green foliage about 1.2 m tall. Tall, fluffy, pale-brown flower spikes are produced through summer, followed by black seedheads. Excellent for naturalising at the margins of ponds and streams.
