Victorian Christmas Bush
- Evergreen shrub or small tree.
- Size: 1 – 6 m high.
- Leaves: bright yellow-green to dark green and paler underneath. They are 4 – 15 cm long, 1 – 3 cm wide, and generally have a toothed or curved edge.
- Flowers: funnel-shaped and white, or pink to pale mauve, with purple and orange spots inside. They are about 2 cm long and grow in clusters at the end of branches. They are slightly scented.
- Fruit/seed: known as a mericarp, it is 2 mm long and contains one seed which is about 1mm long.
What to Observe
- First fully open single flower
- Full flowering (record all days)
- End of flowering (when 95% of the flowers have faded)
- Seeds dropped to the ground (record all days)
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
- From late spring through summer.
- Flowers appear from November to March.
- Fruit appears after flowering.
Where To Look
- In coastal and sub-alpine areas, from southern Queensland to Tasmania.
- In rainforests, forests and woodlands, commonly along watercourses and in moist gullies. It is also found in urban areas, particularly in gardens.
The map below displays the accumulated observations of these species as reported by ClimateWatch observers, together with the layer showing how the range of the species might change between now and 2085, with orange areas indicating where the species might disappear, and green areas where the species range might expand.

Another Prostanthera species (“mint bush”): won’t have fine hairs on the inside and outside of the flowers, which can be seen with a magnifier on the Victorian Christmas Bush.
Did You Know?
The leaves have a minty smell when crushed.
It is known by Indigenous Australians as Coranderrk (Wurrundjeri) and its flower stems were used as fire sticks.
