Will this rose survive temperatures from 19 degree celcius (66 degrees farenheit) to 33 degree celcius (91 degrees farenheit)? Also, how much rain can love and peace tolerate?

My cousin received 2 of these roses in big pots in Minnesota (zone 4!) We read here zones 8 and warmer, but Ping Lim seems to test his things in Minn and it was bought here.
So: does it have to stay in a pot and be brought in in the winter or can it be planted in the ground and warmly covered in the winter?
Any experiences or advice would be welcome.

I know of an alternating hedge in Santa Clarita, CA of Love & Peace, Henry Fonda and Ingrid Bergman that is just spectacular. If anyone in arid, high heat areas wants something dramatic, dense, full and extremely colorful, please feel free to "borrow" the combination. Here it makes a chest high mass of bright color virtually year round.

Fragrance contains mirre scent! Like the Austin Roses.
