I have found this rose to be very heat tolerant. It blooms through months of temps of high 90s and low 100s without pause. It is not a fussy rose and can be pruned to a smaller size than shown in my photo of the plant.
It does get some blackspot when the conditions are right, but not enough to cause the plant to defoliate in my climate.
My plant is budded and I don't know how it would perform own root.
Smiles,
