What plant? : Attachments (1). 5 posts by 3 authors.
I have been seeing this growing out of stone retaining walls on my walks. I am not sure if grows on the ground too-I am yet to come across one. The flower is tiny, not more than 1-2cm. The whole plant in the picture must be 6-7cm.
I imagine if the leaves belong to the same plant?
It should be Argostemma verticellatum
Thank you … for this ID.
Sorry for replying late-I was travelling and had limited access to the Internet.
I found out the only common name for Argostemma verticillatum is in Chinese ‘Xiao xue hua’.
Are we aware of any English name?

Yes, beautiful pics. Never seen on tree trunks in our area.
Thank you … We have them on walls, rock faces, the ground and on the trees. These plants were growing on a wild pear tree.
