About this weed

The Conyza genus has recently been renamed Erigeron (November 2020). There are a number of species of Erigeron that look quite similar in Western Australia. Some are more easily identified than others. This Erigeron is the tallest of them and can grow to about 2.5 m in height. Some Erigeron are hairy and some are less hairy. This Erigeron is not noticeably hairy. Consult a specialist text to confirm identification. All Erigeron were originally from South America except E. canadensis which comes from North America.


Fleabanes are usually easily seen in bushland as they are erect annuals growing to 2.5 m high, with white or cream flowers from January to March. Its stems and leaves are not noticeably hairy and it has an open branching inflorescence.
