Weed of the Week!


Get to know your enemies: one weed at a time, one week at a time…

Rubber Vine (Cryptostegia grandiflora)
Restricted invasive plant under the Queenslands Biosecurity Act 2014
Weed of National Significance 

  • Flowers are a pale pink, darker in the centre.
  • Strangles native vegetation, common and problematic in riparian areas and poisonous to livestock.
  • Very distinctive seedpods that look like pointy dragon wings (green when immature, like the picture on the left – they turn brown as they mature) Seeds inside are white and fluffy like cotton and spread by wind, water and livestock.
  • Rubber vine has a white sap, that can be used to make glue or rubber (hence the name). You can cut or crack a small piece of the young vine to check for white sap for ID, just be careful not to get this on your skin, it can be very irritating to skin.
  • Young rubber vine can look like a small tree with ‘whippy’ arms flying off all over the place. Look for a red central vein on the underside of the leaf. Leaves are opposite.
