Grass-leaved Orache grows to about 100cm high. It bears tiny, greenish flowers of both sexes. The male flowers have five segments and five stamens; the female flowers have two large triangular bracts. These flowers are borne in long, branched, spikes which are leafy towards the base and on erect, ridged stems. The leaves are linear-lanceolate with the lower leaves short-stalked and the upper leaves unstalked. This plant grows on coastal sites and salt-marshes. It is a scarce, native annual found on some East and south-East coasts. It belongs to the Goosefoot family.
I first saw this plant and photographed it at Lady's Island Lake, Co Wexford in 2012.
