Mine has about 3 flushes a year. Definitely a rebloomer. My clone is from Italy, in case that matters :)

I bought this particuliar rose due to its drought resistant conditions. After planting there was some die-off, however it is beginning to grow new leaves, even in the summer of heat of PHX.

Disease free like it's parent without being the "Rose that Ate the South".
About 15Ft at maturity and can be kept 1/3rd. that height.
Reliably thornless unlike some R.banksiae clones. Light fragrance.
Reliably re-blooms in Autumn. Blooms well in bright shade.
Drought tolerant and seems not to need feeding to remain vigorous.
