Water Meadow Grass

WATER MEADOW GRASS (Glyceria aquatica (L.) Wahlb.)

Botanical description:

Water Meadow Grass is perennial, with a very long and thick creeping rootstock. The stems, which generally root at the base, are stout and up to nine feet high. They are leafy to above the middle; the leaves are long and broad. The whole plant has a peculiar bright green or yellowish-green colour. Water Meadow Grass may also be readily recognized by the two yellow or yellowish-brown spots at the upper end of the sheaths.

The flowers are in a spreading panicle, which is sometimes a foot and a half long and almost as broad. Its branches are numerous and carry a great number of spikelets. These are at first yellowish-green but after flowering they are bright brown, sometimes with a touch of purple. A spikelet contains from five to eight flowers, each of Which is enclosed by two glumes.

Geographical distribution:

Water Meadow Grass is indigenous to almost, all Europe and temperate Asia. In North America a closely related species, Glyceria grandis Wats, chiefly distinguished by its smaller flowers, takes the place of Glyceria aquatica and may be of equal agricultural value.


Water Meadow Grass occurs along muddy shores of lakes and streams, Where it sometimes occupies vast areas to the exclusion of other grasses. It makes splendid growth in shallow waters With loose and swampy bottom, Where the creeping rootstocks do not meet any resistance. In dry ground, Where the rootstocks cannot develop properly, the growth is checked and the quality of the grass is poor.

Agricultural value:

Although stout, Water Meadow Grass is rather soft in texture and can be closely pastured by horses and cattle. Especially when young, the stems and shoots are palatable and greatly relished by stock. They are then sweet and highly nutritious. Although its value as a forage plant was recognized in some European countries in the eighteenth century, it is not extensively grown.
