You must live in a place where the climate is suitable for roses - such as WA, OR & even CA.
We once had about 50 to 60 specimen - all named Hybrid Tea Roses, Grandiflora Roses, and even some miniature roases, at the backyard. 2 x 25 each brush roses at the front lawn.
It wasn't a smart move because Houston is not the good climate to plant roses (too hot and too humid). We constantly have to fight the mildew, black spot, athrips etc etc. We even spent $200 mail-ordered an electric spray to be strictly used for fine spraying in the fruitless attempt to stop blackspot.
But that was our first house, so we did silly things. :)
