•Full flowering (record all days)

•End of flowering (when 95% of the flowers have faded)

•No flowering

•Fruiting

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 or unsuitable

Help scientists answer the question: "How are our animals, plants and ecosystems responding to climate change?"

When To Look

Flowering occurs in warm temperatures (September to February).

Fruiting occurs 1-2 months after flowering.

Note: ClimateWatch is looking for any changes in the timing of these events so remember to keep a lookout all year

Where To Look

It can grow in sandy soils, swamps, wet habitats such as the banks of creeks and can be found in open forests and rocky hillsides of VIC, NSW, QLD, TAS.

Widely planted in urban gardens.

Note: ClimateWatch is looking for any changes outside of their known ranges so remember to keep a lookout beyond these regions too!
