Life Cycle and Dispersal
Seed and vegetatively by rhizomes and through nodal rooting (layering) of collapsed flower stems. The seed is easily spread via stock, agricultural equipment, flood waters and hay. Rhizome fragments are also spread by stock, machinery and flood waters. The longevity of the seed in the soil appears to vary depending on soil moisture and other climatic conditions. Rhizome fragments readily survive drought. (Hayes, 2014).
