Originating in tropical America, Morning Glory is a vigorous, twining, herbaceous perennial climber growing to the top of the canopy and forming a dense blanket over all vegetation. Common in moist, disturbed places.

Leaves are large, light green and heart shaped, usually three lobed. Both leaves and stems are hairy. Flowers are distinct violet-blue, 5 to 8cm in diameter occurring anytime in the year, particularly in warmer months. Rarely sets seed in Australia. Spreads vegetatively.


Spreads from dumping on bushland edges. New plants can grow from stem fragments, rooting at nodes where they contact the ground.

Impact on bushland

Has the ability to smother trees and understorey vegetation. This weed is invasive and poses a significant threat to the bushland environment. It may cause distress to neighbouring properties both through the plant stems spreading over boundary lines. Due to the plants' invasive nature, treatment to contain this weed must start immediately. As this weed is likely to continually grow and spread, total removal is recommended.

Control Measures

The growth of the plant must be managed in a manner that reduces its numbers, spread and incidence and continuously inhibits its reproduction and the plant must not be sold, propagated or knowingly distributed.



  • Cut the vines close to the ground and dig out as much of the root system as possible or use the stem scrape technique applying neat Glyphosate-based product.
  • Some regrowth is likely and should be retreated in the same way.
  • The remaining vines in the tree can either be removed or left to rot in situ. Lengths of vine can be coiled up and left off the ground to dry.
  • Note: Do not yank stems running along the ground as rooted fragments will snap off and grow again. Careful follow up needed.

See Manual Weed Control Techniques.

Chemical: Please contact your local control authority for advice on chemical control.

Similar species

Native climbers, Sarcopetalum harveyanum and Stephania japonica, may be confused with Morning Glory. These also have heart shaped leaves, but tiny white flowers. Another native species, found on coastal sand dunes, Ipomoea pes-caprae subsp. brailiensismay also be confused with this weed.

Another weed, Coastal Morning Glory (Ipomoea cairica) has similar flowers with five-fingered leaves.

Suggested alternatives

  • Wonga Wonga Vine (Pandorea species)
