Sea Club-Rush is a perennial herb with horizontal
stems below ground, and can reach 1.2 m in height. It has triangular
stems that are sheathed by sawtoothed emerald-green leaves. Each
individual plant grows from a corm and then puts out a horizontal
rhizome from which the next plant grows. In this way the plant can
quickly form dense stands. Flowering stems rise above the leaves during
summer with golden brown, ovoid spikelets clustered just below their
tips. The flowers are monoecious (individual flowers are either male or
female) but both sexes can be found on the same plant. Shiny brown
tear-shaped fruits are produced, each containing one seed. Sea
Club-Rush is a cosmopolitan weed spread out across the world.
Medicinal uses: The roots or corms of Sea
Club-Rush have been used in China as an astringent and as a diuretic.
