Answer: It's always a challenge to learn what grows in each gardening region, so you're not alone in your endeavor. Arctostaphylos uva-ursi 'Massachusetts' is recommended for growing in your gardening region. It is drought-tolerant (meaning it grows well in dry soils in hot locations). You can plant it and then mulch around the plants with 2-3" of organic material to help slow water evaporation and help keep the roots cool. Once the plants become established, they should adapt to the area without problem.
Best wishes with your landscape!
