Flowers: Its large funnel-shaped flowers (5-10 cm long and 7-10 cm across) are blue or bluish-purple in colour with pale pinkish centres. These flowers have long and narrow sepals (14-22 mm long) and are borne in clusters of two to twelve in the leaf forks.

Fruits/Seeds: This species does not produce viable seed in Australia, and fruiting capsules are rarely seen here.

Dispersal: This plant reproduces vegetatively via rooting stems. Stem fragments are commonly spread by water, animals and in dumped garden waste. They may also be dispersed by slashers, movers and other vehicles.

Distribution: Cultivated as a garden ornamental. Can be found in riparian habitat along waterways and in coastal areas.

Status: Undeclared in Tasmania. However, it is a significant environmental weed in many states and should be controlled before becoming widespread in Tasmania.

Weed Impacts:

  • Smothers vegetation and may hinder regeneration of degraded sites or edges of riparian or wetter areas.

Control Methods:

  • Do not dump garden waste.
  • Practice hygiene control and washdown machinery, tools and equipment.
  • Hand pull small plants.
  • Herbicide Control. Cut stump, stem scrape and foliar spray can all be used to control Morning Glory.

N.B. Always check the herbicide label before use.
