ClimateWatch Science Advisor
We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas, as warmer temperatures enable them to live in environments that were previously too cold for them.
When To Look
- Present all year
- Flowering typically from November to January
Where To Look
- Widespread in the southwest of Western Australia, from north of Kalbarri National Park down to Cape Leeuwin and across to Fitzgerald River National Park.
- Often in sandy soil
