As an additional note on Pimelea mimosa, I have cultivated this species in a wide range of situations (both shade and sun) in Auckland and Hawkes Bay, and found it to be both surprisingly tolerant of both competititon (within reason) and humidity (even in Auckland). Oratia NPN have also found it to be successful in our northern climate.
I felt that could be a useful contribution to the propagation details on the website, as cultivation is important for the future of this species.
