Forms dense thickets, hindering the movement of wildlife and excluding all other plants. Notes: an aggressive, widespread and abundant environmental weed in this region. Seeds are long lived and highly viable. A different subspecies, L. leucacephala subsp. glabrata, is grown as a productive and highly nutritious fodder legume by the grazing industry.
