You would probably be able to do best with the southern highbush types such as O'Neal, Sunshine and Jubilee. However these blueberries are susceptible to spring frosts and may need to be covered to protect them if they start to bloom and a late frost threatens. All blueberries need an acidic soil with plenty of peat moss mixed in, even to a 50:50 mix if practical. They need good quality water and most west Texas sources have high pH or possibly high salts and/or high bicarbonates. Thus rainwater may be needed for watering at least as a supplement. Some shade is okay but for good production you will need quite a bit of sunlight exposure.
As an alternative to the southern highbush, since your winter temps stay pretty cool for a long period of time you may be able to get the regular highbush types to grow there. But I'd still try southern highbush.
Thanks for the question. Please stop in again soon!
