What can I do?

1) Sign up to the Spotter Network at

www.capetowninvasives.org.za

2) Log your sightings on the Spotter Network so we know where the plants are situated.

3) How do I remove it?If you can physically remove the plant, log its removal on

the system so that we know that it has been removed.

4) If you can’t remove it yourself, the Cape Town Invasive Species Unit will send out a team.

Join the Cape Town EDRR Spotter Network

Why is it a problem?

• Prolific seed producer.• Flowers cause respiratory tract irritation.• Sharp leaves can cut skin.• Rapid spread and dense growth-form

means it outcompetes indigenous plants.

How do I remove it?

• Wearing protective gear, mature plants need to be dug out by the roots.

• Ensure all root fragments are removed.• For chemical control, contact the

Cape Town Invasive Species office.• WARNING: Herbicides should only be

applied by suitably trained and equipped individuals.

How does it spread?

• Each plant can produce over a million wind-blown seeds.

• Tolerates very poor soil.• Large, rhizomatous roots resist fire.

What if I can’t remove it myself?

Join the Spotter Network and the Cape Town Early Detection and

Rapid Response (EDRR) unit will send out a team to help you.
