The common name was coined originally for a cultivar of the species selected for its success as a pasture grass under relatively dry, poor conditions, but the name has since commonly been applied to all strains of the species occurring in southern Australia.
Hybrids occur between L. rigidum and both L. perenne and L. multiflorum, the chief contributions of L. rigidum to the hybrid being typically a reddish pigmentation of the stem, a slightly longer than normal glume, and the annual life-form.
