Thanks Jonna. The advantage of including a large number of natives is that they're right for the climate and readily available. I've been going back through my old photos and have dug out some shots of these plants and their flowers, etc.
This is the flower of Syzigium suborbiculare
Flowers of Allosyncarpia ternata
Flower of the Bauhinia, the same tree as I got the seeds from for my plants.
I'll post some more when I locate other photos.
