Suitable rose / clematis combination for trellis arch
I have a trellis arch which I am looking to cover, and understand that for full coverage roses and clematis are recommended. I have a couple of questions... Firstly, are climbing or rambling roses better? I am looking at planting 'The Albrighton Rambler', has anybody used this for an arch? Also, I am looking at combining with the clematis 'Etoile Violette', but purely because I like the colour, is this a combination that any of you have used before or is there a better combination that you could recommend?
Many thanks in advance! Emma x
