Self-sown vine growing over tree stump for at least 25 years. Other specimens seen around the property. Flowers appear in bunches, with strong honey scent. The flowers attract many different insects.
I don't believe this vine to be Araujia sericifera. The flowers on it are far bigger (?30x) than the the flowers on this vine (Sg 4640075). The leaves on my vine are much bigger, and look glossier and thicker than the A. sericifera leaves.
Just keyed this out to find Tapirlord had come to the same conclusion. Great to know my 1st 'it felt successful' keying out exercise was exactly that. Thanks to Tapirlord & Plantnet NSW.
