ClimateWatch Science Advisor

We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. Introduced weeds 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

  • Twisted leaves can been seen sprouting from the ground all year.
  • Flowering is between August to October

Where To Look

  • Introduced weed found in Western Australia.  Native distribution in South Africa.
  • Ranges from north of Perth, inland to Albany Highway, south to Mandurah.
  • Also found near Dunsborough.
  • Look among tall – medium trees and shrubs.
