The roses can make it if you get the right variety and plant at the right time of year in the right location. The problem is that we should be planting stuff in early February but the plants don't come in until later and don't have a chance to become well established before the heat sets in.It's best if you are going to plant any trees or shrub's to plant the one's that will actually grow well out in the desert. I love roses and those Peonies, but I also know that they aren't right down here with this heat.
