This has been on my nature strip for 20 years and never flowered. Usually a few small clumps but it has gone crazy with 4 years of above average rainfall
Thanks for identifying it I thought it was but as it never flowered, I could not be sure. The reason is it is dioecious and needs a male or female plant around it. Not much chance of that in the middle of a suburb. It is nice to know it has survived on my nature strip though.
