Triglochin maritima is a variety of arrowgrass found in brackish marshes, freshwater marshes, wet sandy beaches, fens, damp grassland and bogs. It has a circumboreal distribution, occurring throughout the northern Northern Hemisphere. In the British Isles it is common on the coast, but very rare inland.
It is like Triglochin palustris but has the following differences: it has stolons, is stouter. The leaves are fleshy and not furrowed above. It is not very aromatic. The raceme are more dense and like Sea Plantain. The flowers are fleshier. The fruits are oval, 4mm long, 2mm wide.[1]
It varies in height from 8-30 inches (to 45 cm). It flowers in May to August; flowers are greenish, 3 petalled, edged with purple, 1/8 inch (2mm) across, in a long spike.[2] [3] Common names include Common Arrowgrass, Sea Arrowgrass, Shore Arrowgrass and Seaside Arrowgrass.
It can be an annual or perennial. [4]
