Forest bluegrass
(Bothriochloa bladhii subsp. glabra)

  • suited to traprock soils of southern Queensland
  • persistent under grazing
  • competes with poorer native grass. 

Forest bluegrass (Bothriochloa bladhii) is a natural component of the better speargrass country, but subspecies glabra cv. Swan is an introduced species. Swan has moderate spring vigour, and persists under heavy grazing despite being well eaten by cattle.

Although this leafy perennial was first selected on the infertile traprock soils of southern Queensland, it is more widely adapted.

Swan produces a fluffy small, but high quality, seed in late March, and can spread from seed and short rhizomes into run-down native pastues of pitted bluegrass (Bothriochloa decipiens).

While the seed head is not affected by disease, the leaves can be attacked by leaf rust (Puccinia spp.) late in the season.
