they would be bare in the winter so unless you plant other things for interest in the spring it would be plain. chose roses resistant to fungal diseases to make looking after them easier. Then obviously you have the pruning in the spring. Not my personal taste but done well they can be stunning.
What about mixed shrub border instead?

Never thought of that . Would it give me enough colour? What shrubs had you in mind?

Some people like to underplant roses with winter flowering pansies or violas, and/or spring bulbs.

I have lots of favs from skimmia, dogwoods, osmanthus, sarcoccocca, Euyonomous [spelling?] azalea, camellia, hydrangea wigellia, spirea [bridal wreath]. there are lots but depends on your soil type etc. Some can be quite small whilst others can be pruned to fit space.

look at the shrubs mentioned on here :o)

I think SBGirl,s idea would look lovely I have a few of her suggestions and they are pleasing all year round .

Thanks SBG , I will look into that idea. I do have Darts Gold, Sambuccas and a few other shrubs in other borders and they are very easy to look after.

you could have a border containing roses & shrubs, the shrubs will give you year round interest and the roses can give you extended flowering season depending on the weather :-) roses are not hard to care for they just have a bad reputation

Thanks Greenfinger I had thought of that also. I have a few climbing roses that I bought about 2/3 years ago so Im hopeful one day of having a glorious display of them over my fence ( Oh how I dream!)
I actually grew a white rose from a bouquet last year and produced a few flowers. I was so pleased.
