Qld Blue CouchQueensland Blue Couch is not from Queensland nor is it a couch as its' name suggests. It is a tropical grass originating from the Canary Islands.
It grows best in full sun, thriving in sub-tropical conditions and high humidity, and has a natural ability to limit weeds, with the sward growing up to 20cm tall with very dense leaf if not regularly mown.
The leaf blade of Queensland Blue Couch has a blue/green appearance, is soft to touch and grows up to 30mm long and 5mm wide giving it a fine to medium texture.
Queensland Blue Couch is stoloniferous (not rhizomatous), which makes it less invasive of garden beds.It produces long runners on the surface of the soil which develop roots at the nodes.


Qld Blue CouchQueensland Blue Couch produces minimal thatch and does not suffer from a patchy appearance after mowing as some varieties of Green Couch do. If well maintained, Queensland Blue Couch will have a rich blue-green colour and will produce a dense mat resistant to weed invasion.
If neglected Queensland Blue Couch is a reasonable performer and will recover well from periods of extended dry weather, responding extremely rapidly to rainfall.
Queensland Blue Couch tolerates a wide range of soil types but has a definite preference for lighter soils. It will also tolerate low nutrient levels and moderately low pH.
With a little extra care Queensland Blue Couch can provide a very attractive, manicured appearance and makes an ideal lawn for residential and commercial properties.
Queensland Blue Couch occurs naturally in South-East Queensland where it is often the variety of lawn found in the older suburbs of Brisbane and surrounding regional centres.


The mowing height for Queensland Blue Couch should be set at 15mm - 35mm. In domestic situations a height of 20mm - 25mm is ideal. Mowing frequency is 7 -14 days in the warmer months and 21 - 28 days in the cooler months. The mowing height should be raised in winter when the grass is growing slower, to enable better photosynthesis in the reduced daylight hours, and lowered in summer when it is growing faster and daylight hours are longer. It also requires none to absolute minimal de-thatching (vertimowing) when compared to every other Warm Season Grass.
