Lots of rose varieties are adaptable to low desert gardens. My favorites include
Peace, Chicago Peace, Christian Dior, Perfume Delight, John F Kennedy, Queen Elizabeth, Mr Lincoln , Angel Face, Roseberry Blanke, Lowell Thomas and Arizona. Just look for the color and the scent you like and go ahead and plant them in your garden. The site you describe sounds as though it might be just right. Roses need at least 4 hours of morning sun in order to bloom well and most appreciate shade from hot afternoon sunshine.

The best time to plant bare-root roses in the low desert is mid-December through February but you can plant now, before it gets too hot. You'll need to prepare the soil well prior to planting. Dig the hole at least 18?30 inches deep and 18?30 inches wide, depending on the size of the rose. In the bottom of the hole, add 1 cup superphosphate fertilizer and mix it in with the soil.

Create a soil mix to fill in the hole. You can simply mix half native soil and half compost mulch together, or you can mix one-third each of native soil, compost, and sand, perlite, or pumice. The most important feature is good drainage and these ?recipes? from ASU will promote that.

Add two or three shovels of the soil mix to the planting hole and make a cone shape at the bottom of the hole. Spread the roots of the rose bush over the cone. The bud union should be about two inches above the soil level to prevent possible disease. The bud union is where the rose was grafted onto the rootstock. It is usually noticeable as a slight bump or raised area.

Cover the roots with the rest of the soil mixture, firming the soil around the bush. Mounding with moist mulch protects the canes from drying out while the root system is becoming established. Leave this on for 14?21 days. Water slowly and deeply to eliminate air pockets and prevent the rose from drying out.

Best wishes with your new roses.
