Ground Cover
Natural Distribution: 
Native to tropical South America.
Description: 

Once this vigorous, smothering climber takes hold it is perhaps the most difficult of all Taroona's weeds to eradicate. The privately-owned passionfruit-infested gully at the bottom of Jenkins Street has even been informally named "Passionfruit Gully" by TEN.  Passionfruit Gully has been given attention by TEN and neighbouring residents for over a decade, attempting to bring the vine under control. This continues to be extremely difficult in such a steep-sided, damp gully. Other Taroona gullies suffer similarly from this weed, including the Crown Land gully between Karingal Court and northern Flinders Esplanade.  

Banana passionfruit bears large pink flowers during summer, which turn to green, oblong, banana-shaped fruits - becoming yellow when ripe. Each fruit contains up to 200 seeds.

Dispersal:  Its seeds are spread by birds and animals - after passing through the digestive tract. Also spreads in dumped garden waste and soil. 

Control:  Dig out or cut and paste ALL stems. This is very difficult with large infestations. In such situations, it is best to tackle the infestation in narrow strips, advancing from the outside of the infestation, toward the centre. Remove and bag all fruit. Vines draping on branches that are not in contact with the soil can be left to dry.

Safe Alternative:  For lovers of passionfruit, the round, purple variety is safe to plant.
