Marine couch

Other names (PBR name, trademark, breeder code)

QLD-Coast (formerly protected by Australian Plant Breeder's Rights); MR-S2 (breeder's code).


Under favourable conditions, 'QLD-Coast' is fast spreading, producing a moderate to tall canopy that is dense while proudcing few seed heads. Under optimum management the plant provides a dense sward and can be cut at a range of heights from 5-30 mm. The plant responds well (improvement in turfgrass quality) to the use of poorer quality water and under correct management it is likely to perform under greens (golf and lawn bowls) conditions.

Other comments

Sporobolus virginicus is an Australian native grass. 'QLD-Coast' was discovered in July 2004 by Matthew Roche as a plant growing on the foreshore within Redland City, Queensland. The location from which the Sporobolus virginicus ecotype was selected was partially submerged in sea water as a result of changing tides. The plant was selected on the basis of its compact and dense growth habit, along with its suspected salt tolerance.
