Native Morning-glory or Poison Morning Glory

Ipomoea muelleri

Appearance

  • Sprawling perennial ground cover.
  • Size: up to 3 m wide, with twining stems.
  • Leaves: Heart shaped dark green leaves are up to 4 cm long and 2 to 3 cm wide.
  • Flowers: Lilac or pink flowers have a darker throat and are shaped like a funnel or trumpet.  Flowers are up to 4 cm long and 5 cm in diameter.

What to Observe

  • First fully open single flower
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)
  • Not flowering

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

  • March to December

Where To Look

  • Extends from Carnarvon in Western Australia east to the desert and north-east to the Kimberley and Northern Territory.
  • Look in alluvial loam or gravelly soils in shrub and steppe country.  Also look along river courses.

Above, the left and middle maps show the modelled habitat suitability for the the species under current and potential future climate conditions. The colours indicate the predicted habitat suitability from low (white) to high (dark red).

The future habitat suitability is modelled for the year 2070 under a climate change scenario that represents 'business as usual' (RCP 8.5). The map on the right shows how the range of the species might change between now and 2070, with orange areas indicating where the species might disappear, green areas where the species range might expand, and blue areas where the habitat is predicted to be suitable for the species now and in the future.

The models for this species were run in the Biodiversity and Climate Change Virtual Laboratory. Please note that while models can be very informative, they are only a representation of the real world and thus should always be viewed with caution. You can read more about the science behind these models here.

    Related to the bush potato (Ipomoea costata), a twining shrub up to about 2 m tall which grows in rocky outcrops near Dampier and further inland.

  1. Did You Know?

    Poison Morning Glory is toxic to stock and has caused heavy sheep losses in Western Australia.

    Ipomoea is from the Greek 'ips' or 'ipos', a worm that eats horn and wood, and probably refers to the long slender stems.

    Poison Morning Glory refers to its toxicity and the morning opening of the showy flowers, followed by their closing in the afternoon.
