Welcome. You have a very interesting climate. If I should translate where you live into our, European terms, you have Southern France/Croatia summers and Croatian winters (rainy).
That's one interesting and good climate. Not only that you can grow many ornamentals, but also many edibles as well. If I were you I would go ahead with Orinoco (or any other O. variant), Dwarf Brazilian...
Those varieties would almost surely fruit in your climate without any problems and you would have another use for these wonderful plants, besides looking good and fancy.
Sorry, but I can't answer your question about ornamentals.
