Thanks Michael - this is not on our rare plant list but maybe it should be, There is only one ACT record of this plant in the Atlas of Living Australia a 2006 recording by Isobel Crawford also on Lake Burley Griffin at Acton. It is not listed on the ACT census of vascular plants and is mainly a coastal species.

Hi Michael. PlantNet says it is a Native of South Africa. But it is an easy to recognise one with its distinctive colour.

Thanks Michael - I should have checked the symbol -will also check out whether it has been subject to a weed risk assessment

If you look at the other sighting, you will see that it can be quite dominating and copes very well with mowing. There was a dense patch of it maybe 30 metres across. See http://canberranaturemap.org/Community/Sightings/Details/3342917
