Life Cycle Comments
Perennial; produces strap-like leaves in winter which die down in the summer months (Fromont and King, 1992).
Reproduction
Reproduces by two means: produces small cormils on the flower head and sends out creeping rhizomes to extend the colony (Fromont and King, 1992). New cormils are also produced on the original corms which are able to be transported by any soil disturbance (Fromont and King, 1992).
Seed
Produces no seed (Fromont and King, 1992).
Dispersal
Soil movement (road graders, fill), vegetation dumping, water movement.
Tolerances
Moderate to highly tolerant of shade; tolerant of frost and moderately dry conditions (Fromont and King, 1992).
