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.

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.
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.
