Mist Flower is a perennial herb that forms dense ground cover in moist, shaded areas. It spreads aggressively via creeping stems and produces masses of wind-dispersed seeds. It is particularly problematic along waterways and in rainforest understoreys.
How to Identify
- Low-growing herb 0.5-1 metre tall
- Opposite, triangular leaves with toothed edges
- Clusters of small fuzzy white flowers
- Purple-tinged stems
- Creeping stems that root at nodes
- Fluffy white seed heads
Where It Grows
Shaded, moist areas including creek banks, rainforest understoreys, and wet gullies.
Environmental Impact
- Forms dense monocultures excluding natives
- Spreads rapidly by both seed and vegetatively
- Difficult to remove once established
- Alters habitat for native fauna
- Spreads along waterways
Control Methods
- Hand pull small infestations (remove all root material)
- Foliar spray for larger areas
- Mulching can suppress regrowth
- Time treatment before seeding
- Multiple treatments usually required
- Biological control agents available
Seasonal Activity
Flowers mainly spring and summer. Seeds disperse autumn.
