|Will they survive here?|
|You can grow plumeria in Prescott, if you give it the proper care. I grow one in a container in Phoenix. My plant spends the year on a south facing covered patio where it receives sun most of the year and full shade in mid-summer. It is brought inside when temperatures under 35 degrees F. are forecast. You can do the same with yours.
Best wishes with your plumeria.
