Hello Arturo,
I would recommend OGR's as I have been a strong advocate for these old roses since I started
growing roses. I have only grown about 3 or 4 Hybrid Teas or Grandifloras in my Garden, I have
pretty much stuck to China roses, Bourbon and Tea Roses. Of course this is in Houston, TX where we have blooming roses from about March through and past Christmas. In your case I would be looking at
a lot of the OGR's that just bloom once or occasionally like the Centifolias and the Damask Roses
That is what I will do if my better half when she retires decides to move us to Bend, OR which is
much colder that Houston, TX It would probably be more like what you experience in Argentina
