Profile last updated: 17 Sep 2019


Bomaderry Zieria is an 80 cm tall shrub, with clover-like (trifoliate) leaves that are covered in velvety hairs. Each leaflet is rounded and blunt, to 12 mm long and 9 mm wide, with curled-under edges. Shrubs produce masses of small pinkish-white flowers between September and October, arranged in clusters of three to seven.


The species occurs in only one location north-west of Nowra. The population occurs in a total of 43 colonies in six discrete clusters. These clusters are confined within a 0.5 km x 1.0 km area of the bushland, and are found on both sides of Bomaderry Creek.

Habitat and ecology

  • Bomaderry Zieria occurs on skeletal sandy loam overlaying sandstone, on a rocky plateau amongst sandstone boulders in either shrubby open forest, shrubby woodland or closed scrub.
  • Seed production has never been observed in the Bomaderry Zieria and all evidence collected to date suggests that the species has lost its capacity to reproduce sexually.
  • Plants resprout following fire.
