Habitat and ecology

  • Grows in floodplain areas on heavy soils and may rely on appropriate and intermittent rainfall and flooding events for its survival. The species is described as being a summer-growing annual and is thus dependent on seasonal conditions.Often associated with open grasslands and eucalypt woodlands in or near creek beds, and grassy flats and levees near watercourses.
  • Flowering time is spring to summer, and the species is a summer-growing annual. Seeding is recorded in March. Occurs after summer rains and readily drops its leaves as it dries off.
  • Plants are usually infrequent in abundance but have been recorded as common in disturbed areas.
