Lesley the location within suburban Warramanga does not seem to match the images. Can you please check and see if the location needs to be edited. This is rarely recorded in our region, but is a major weed elsewhere in Australia, such as the Adelaide Hills. It would be good to either pull out the two plants (wear gloves) or treat before it spreads further. It is a host plant of the Monarch Butterfly which is another non-local species that is occasionally recorded in our region.
Hi Michael Thanks for Iding that. My GPS is obviously incurate on my phone as I was on Urambi Hills :-( I will see if I can fix it then get Steve Taylor to go out and remove them. THanks !!
