Captain,
Most likely Southern Highbush,like Sunshine Blue,Misty,Emerald.The list goes on.
Legacy is a hybrid,so it sort of falls in that category.
Your area looks to be in Zone 9.
Are they going to be in containers?I'm not sure what the soil is like there,but if it's like a California type,alkaline,then that might be best. Brady

Yes, I was planning on containers, the soil here (if you can call it that) is not good for much without a lot of amending. They are approx. 22" x 24" hopefully that is OK.

C...actually, planting in containers (blueberries) is probably a great idea. Planting in an acidic medium is very important! The easiest way to do this is buy an azelia/camelia potting soil. I know Az can get intensely hot. Maybe placing your pots in a location that filters the afternoon sun would be a good idea. goodluck

You will need to test your irrigation water for pH, to be successful with blueberry shrubs. If you are on a municipal supply, that information should be available for free, from the water utility. If you can collect rainwater, or snow-melt, that would be best for watering your blueberry shrubs, because it will be slightly acidic or pH neutral. If you are using well water, or tap water that contains dissolved limestone, you may have to periodically add a small amount of sulfur to your soil mix to maintain acidic soil pH. At some point, you will have to do pH testing to see where the process is at. This is not very hard to learn, and not very expensive, either.
