thats a hard ask . perhaps one of these honey suckles that generaly stay green all year unless its realy cold .bigger the pot the better to .you could mix a couple of colours . sorry im know good at latin names as im dyslexic .

Trachleospermum jasminiodes might fit the bill, but where you live, I'd wait till spring to plant it. Evergreen, fragrant white flowers in summer, needs something to climb up, bit slow to get away initially, once its got going, its fine. Won't like lots of northerly or easterly winds in the winter much though.

Clematis armandii, which, if it's given a good start, will rival most things for vigour, and early season flower. Phil

I have a Lonicera japonica, an evergreen climbing honeysuckle. It's great, grows fast and the leaves are a super dark green. And the flowers are perfumed. But I believe it needs a bit of shelter before it takes off.

Stroller has just posted a pic of Trach Jasm Bamboo, it does look a lovely shrub.

yes, it is a beauty - well behaved, slight russet tint to the leaves at different times of year, glossy leaved, and lovely fragrance in summer when in flower.

thanks for all you suggestions. We currently have a couple of honeysuckles, but they havent performed very well since we got them, which makes me question whether i want them elsewhere. I think i'll look into the Trachleospermum jasminiodes and the clematis.

Thanks again, i have some thinking to do now x

Trachelospermum is lovely but don't know if it will like being outdoors as far north as Lancs. If you have a warm sheltered spot you could give it a go. The clematis would be better I think (although I have had them go black in the winter if its cold winds) and it does grow fast. What about Akebia Quinata. Semi-evergreen, grows fast, lovely vanilla scented flowers and grows in shade too. Would need a big pot though. Solanum Glasnevin? might work also. Also, there is a lovely rose...Veilchenblau which is almost evergreen, grows fast and has lovely purple scented flowers all over it. It isn't thorny either.

I would suggest the Clematis too, also the Clematis Cirrhosas are evergreen and would flower during winter and have finer glossy evergreen leaves the rest of the year.
