Training against a fence help

Good morning @Jupes my friend our fellow Rosarian @Sheal is also a Rose expert and always gives sound advice it is possible to grow a shrub Rose and train it to be a short climber ( there are a number of shrub Roses like this) but our friend @Sheal is right a small climber would Fan out more and you would get a better shape all round

You could consider training a couple of modern shrub roses such as hybrid musks, tying their shoots up as if they were climbers, cutting back those that flower quite zealously and feeding them after their first June flush of flowers to encourage a second batch in late summer. 'Buff Beauty' (soft amber/apricot) does well as a ''pretend'' climber, as do 'Prosperity' (white) and 'Penelope' (pale pink).
