You might want to visit the Sacramento Cemetery Rose gardens ... especially for the spring celebration ... to see roses that are doing very well in a hot, dry climate. I am more familiar with the old rose garden which consists of roses found all over the gold country on old homesteads and cemeteries to see if you might find something that you might like to grow. I know they have a modern rose garden there, too.
You can visit a couple of times a year and see how the plants are doing in the heat.
There are a lot of roses that are more shade tolerant than the hybrid tea class.
I haven't found a spot in my garden where succulants can thrive because I don't have enough shade.
