Are those Felicia type daisies (middle picture) a native of Australia? I did not know that. I have several of the blue ones.
We grow all manner of Cordylines here. Some are rather expensive to buy which surprises me as they are easy to grow and reasonably common. Cordyline albertii springs to mind. I have another expensive one called Pink Champagne that cost a bomb. It is thin-leaved and subtly variegated with pinkish leaf-bases. Now it is 9 years old and the pink is no longer. It has a thin, tortured looking trunk and sparse leaves.
The native to New Zealand Cordylines have massive trusses of white flowers in summer that smell heavenly. A heavy, tropical scent that hangs in the warm air. Love it!
