Uniquely identifiable characteristics

Distinguishing Feature :

No relation to : Frog Rush [a plant with similar name].

Flowers late June to early September. The colour of the sepals varies depending upon the moisture conditions of the soil: yellow-green in wetter sites, and red-brown in drier ones. The yellow-green ones give rise to the latin name viridis.

Habitat in the South is on grassy places and short turf on limey soils, elsewhere it grows in meadows, mountain ledges or dunes. Flowering in specific places is erratic from year to year, but sometimes individual specimens can flower 7 years contiguously.
