climbing rose

My husband and I are thinking of planting some climbing roses in our patio. We have already nailed latices on the not so pretty concrete walls (although it has been freshly painted, it is just very cold-looking).

However, there are a few problems...1) the roses must be planted in pots, 2) the patio is half-shade, 3) we have to wait until Oct to plant, since it's waaaay too hot here.

I am wondering how many roses I would need to cover the entire walls. 2? 3? I love antique or David Austin-like roses. I am thinking of Nahema, Mme. Alfred Carriere, and Abraham Darby. I believe all of them are desease torelant, and do OK in half-shade.

Nahema is the first picture with gorgous light pink flowers (with apparently amazing fragrance.). Mme. Alfred Carriere is pale pink, which changes to white as it opens. In the picture, it looks more pink, but it apparently is pretty much white. Abraham Darby is classy, romantic peach that makes me think of Pre Raphaelite paintings. I just love anything between the mid 19th century to early 20th century......
Anyway, I want all of these roses.....but are 3 roses too much for the space????

I also wonder how big the pots should be, since I am assuming that the roses will be very large, eventually.

Ahhh I cannot wait to see my patio covered with beautiful flowers and the aroma. Plus I get to decorate the house with the roses too.....
