A climbing rose is usually repeat flowering, needs pruning late Feb/early March, and really are just taller than usual roses; a rambling rose tends to have smaller flowers which come out all at once, in one main flush, then doesn't flower again until the following year, apart from occasional (if you're lucky) odd blooms later the same year, and over time, may form a thicket or hedge of (usually) thorny branches, should be pruned in September.

For an arch, a climber would probably be best, but check the height and spread - some of them want to spread a fair bit, so choose one that doesn't.

If you want pics have a look at some suppliers websites or catalogues. David Austin has some nice climbers or you could look at Friars Roses for example. There are lots of others.

I have a lovely scented climber that might look well beside the red rose. Its called 'Sunrise' and I got it from Style Roses (online). http://www.growsonyou.com/photo/slideshow/312785-climbing-rose-sunrise/member/cottagekaren
