I am in CA, but in zone 8/9, I moved from the coast and it gets hot where I live now and somewhat cold in the winter at night, it's taken some work finding what grows in the heat. My yard had nothing and I like plants that flower or have some color and stay green all year. I have had success with different lavenders, different lantanas, Japanese boxwoods, citrus trees (tango, oranges, lemon, lime, mandarins, grapefruit), raspberries, strawberries, bougainvillea, salvias, blackberry bushes, ornamental grasses, tomato plants, butterfly bushes, rockrose bushes, blueberry bushes, Mexican sage, heavenly bamboo, cape honeysuckle, azaleas, hydrangeas next to my house in pots, apple trees, palm trees, geraniums. We don't have any real roses, but my daughter picked out one called brilliant pink iceberg rose and it's growing well here with tons of big showy flowers, she loves it. There are other iceberg roses in different colors too.
I thought my list might give you some ideas. Maybe some of these will work for you.
Oh and I have found it useful to find an actual plant nursery and avoid places like Home Depot because the nursery people know what plants are native and have tons of variety. There's one in the hills near my house and it's 35 acres of native plants, everything I wanted I couldn't find until I went to see them and the prices are great.
