Bitou Bush Chrysanthemoides monilifera subsp. rotundata
Bitou Bush is a well-known invasive species that continues to impact our coastal environments here in NSW. Originally introduced from South Africa to help stabilise dunes, it has since spread aggressively and now poses a serious threat to native ecosystems.
What to look for:
– A dense, sprawling shrub growing up to 2–3 metres tall
– Fleshy, bright green leaves with rounded or slightly toothed edges
– Yellow daisy-like flowers (mainly spring–summer)
– Small green berries that turn black when ripe
Where it grows:
Bitou Bush is commonly found on coastal dunes, headlands, and in disturbed sandy areas. It thrives in full sun and poor soils—exactly the conditions many native plants also need, which puts them at risk.
Why it’s a concern:
– Outcompetes native vegetation and reduces plant diversity
– Disrupts natural dune movement and soil conditions
– Degrades habitat for native wildlife, including threatened species
– Can dominate large areas if left unmanaged
Managing Bitou Bush:
Coastcare groups, MidCoast Council and other volunteers are working together to control Bitou Bush through a combination of approaches:
– Hand-pulling: Ideal for young plants and small infestations (best done before seeding)
– Cut and paint or foliar spray: Herbicide treatments for mature plants or hard-to-reach areas
– Biological control: Natural insect predators like leaf-rolling moths are being trialled to help suppress growth
– Ongoing monitoring: Regular follow-up is essential to prevent regrowth
– Replanting with natives: Helps stabilise dunes naturally and support biodiversity
