Answer: Perennials typically have a specific bloom period so you'll have trouble growing something that flowers most of the year. Most need a few weeks to a few months of rest before they're able to produce another dazzling display. I would plant several perennials plus a few annuals so there's always something in bloom. Heat loving plants suitable for your growing region include African Daisy (Dimorphotheca aurantiaca), Blanket Flower (Gaillardia grandiflora), Cleveland Sage (Salvia clevelandii), Desert Marigold (Baileya multiradiata), Damianita daisy (Chrysactinia mexicana), Fortnight Lily (Moraea bicolor), Trailing Lantana, Mexican Sunflower (Tithonia fruticosa), Moss Verbena (Verbena tenuisecta), Mount Lemmon Marigold (Tagetes lemmonii), Parry's Pennestemon (Penstemon parryi), Vinca minor, and Paper Flower (Psilostrophe cooperi). Choose a few of your favorites from this list and pop in a few annuals, changing the annuals as the seasons change. This will give you some color and interest in your flower boxes all year around.
