Morning glory - purple (Ipomoea indica)

Profile

Impact

Purple morning glory, native to South America, is a vigorous perennial climber that can form either a dense ground cover or climb high into the canopy smothering native vegetation.

Purple morning glory reportedly grows in a wide variety of soils and situations. However, it prefers moist areas - particularly nutrient rich sites. It is commonly recorded in urban areas, wasteland, along roadsides and on rainforest margins.

It was widely cultivated as a garden ornamental and has become naturalised in many coastal areas.

Toxicity

Purple morning glory is toxic to humans, causing discomfort and irritation but is not life-threatening. The seeds are poisonous if ingested, causing visual distortion, restlessness and nausea. 

What to do if poisoning occurs:

  • If the patient is unconscious, unresponsive or having difficulty breathing dial 000 or get to the emergency section of a hospital immediately.
  • If the patient is conscious and responsive call the Poisons Information Centre on 13 11 26 or your doctor.
  • If going to a hospital take a piece of the plant for identification.
