It looks like honeysuckle to me too. Clematis Armandii has longer leaves.
Hi Elizabeth. You need to leave this alone except for feeding until it has flowered and you have had the chance to identify it. Then come back on the forum with a photo of the flowers. When you have identified it, you will know whether it flowers on this year's wood or last year's, which is key to knowing how and when to prune it. Hope you enjoy your year's gardening.
Look at the way the stems twine round themselves, and the shape of the buds, and the leaves. This is a honeysuckle.
As busy lizzie says C.armandii has larger leaves. Much larger leaves and a different overall look to it. Most of the other evergreen clematis have the ferny leaves mentioned by Rosa C.
Thank you so much everyone for your expert advice,will keep you posted on its progress. can,t wait for it to flower xx
