Sarga leiocladum

Scientific NameSarga leiocladum
Common Name(s)Native Sorghum, Wild Sorghum


"Perennial. Rhizomes absent or present, short. Culms 60–150 cm tall, 3–5 -noded. Mid-culm nodes bearded." (Simon, B.K. & Alfonso, Y. 2011. Ausgrass2)


We harvest and provide the seed of Sarga leiocladum to rehabilitation works on more natural sites where substrates will be topsoils or materials from shallow depths. In these situations, the seed successfully germinates and grows. Otherwise we are not sure how it may perform on mine spoils with elevated salinity.

Sarga leiocladum occurs on soils of very different qualities. It may be noticeably present or dominant on acid, very shallow soils of rocky ridges with parent rock of granite or metamorphic origin. On soils from intermediate rocks like andesite, this taxon will be present from shallow soils of ridge tops to the deepest soils of stream banks. In basaltic areas it is a varying grass component on approximately neutral to alkaline, clay loams. These are sometimes skeletal soils on ridges, often with Eucalyptus melanophloia woodland, grading to deeper increasingly fertile soils, eventually to fertile, heavy, black, self-mulching clay loams. S. leiocladum often occurs with other the dominant grass taxa, Themeda triandra, Capillipedium spicigerum, Bothriochloa bladhii subsp. bladhii and Dichanthium sericeum, the latter being confined more to deeper soils. Flowering is usually synchronous with Themeda triandra.

Sadly, we increasingly observe the encroachment of the invasive exotic, Dichanthium aristatum (Angleton Grass) on to the deeper of these clay loams.

Historical Notes


Coastal and subcoastal distribution from Mount Mulligan in Queenslands far north to Snowy River National Park in Vic. Extends west into the central Queensland coal mining districts west of Dysart. Seen in a few isolated far western locations also in Qld.
