  • vigorous creeping grass for high rainfall areas
  • more tolerant of waterlogging than signal grass
  • tolerates very acid soils
  • liked by horses.

Brachiaria humidicola (Rendel) Schweick. - 1 habit leafy steams; 2 inflorescense.

Although officially known as Koronivia grass in Queensland and throughout the Pacific, graziers in north Queensland now generally refer to it as `humidicola'. The released cultivar is Tulley.

Although it has been released for the humid tropics, humidicola will grow as far south as Brisbane; however, it is not frost hardy and its cool season growth is lower than that of signal grass.

Humidicola is a stoloniferous perennial that roots strongly at the nodes and forms a tight sod. The leaf blades are mostly smooth, narrow and folded, and rise to a sharp point at the end. The foliage appears rather hard, but cattle readily eat humidicola and horses prefer it to signal grass.

While signal grass is a softer more productive species, humidicola is more tolerant of waterlogging, salinity and very acid soils. It is very resistant to heavy grazing, standing high stock densities over the wet season, indeed it should not be allowed to become too rank. It is aggressive against weeds and also legumes, except for hetero.

Humidicola was planted from runners, but seed is now available.
