Purple morning glory, is a vigorous perennial climber that can form either a dense ground cover or climb high into the canopy smothering native vegetation.
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:
Purple morning glory is a perennial vine with twining stems that are sometimes hairy.
The leaves are hairy, up to 17 cm long and 15 cm wide with a pointed tip and heart shaped base. They may be broadly oval shaped or with 3 deep lobes.
Flowers are funnel-shaped, violet-blue with paler lines on the petals and up to 8 cm in diameter.
Flowering is from spring to autumn.
Purple morning glory grows in a wide variety of soils and situations. However, it prefers moist areas - particularly nutrient rich sites. It grows 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.

All of NSW | General Biosecurity Duty All pest plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable. |
