Common Nardoo
weed identification
Can be confused with leaves of some species of clover. Fronds clover-like with 4-leaflets up to 3cm in diameter. Native Australian aquatic plant that is not normally problematic, however can pose an issue in nutrient-rich environments
Prefers slow moving water bodies such as ponds, dams, freshwater lakes, and wetlands.
Reproduces via spores. The sporocarps protect the spores during dry periods. They open readily once wet and release the spores into favourable conditions. M. drummondii displays vigorous growth, yet does not compete with other water plants.
Spores need to be submerged in water to germinate.
Common Nardoo attracts frogs to the garden, providing good breeding habitat.

Disadvantages of Common Nardoo
Full coverage of a pond or dam by Nardoo is uncommon but may cause significant problems such as:
- Reduce oxygen diffusion
- May shade out submerged vegetation
- Provides breeding ground for mosquitos
- Changes the water chemistry to favour harmful algae and bacteria
