Ideas please for these tired-looking pots ....

I have three of these pots placed along the East-facing wall of our bungalow in Dorset. They were planted up ten years ago - two with the rose Gertrude Jekyll and one with the clematis Abilene. In past years they have been lovely, but I suspect they will never regain their vibrancy and want to use the opportunity for a change, I would love star jasmine - but imagine they would be too vigorous? Something evergreen would be nice, but any ideas appreciated. They get morning sun until around midday.

They might perk up if you can move them into bigger pots with some fresh soil-based compost (or into the ground if you have space). 10 years is a long time in the same pot.

They will be cramped and starved and probably thirsty too (terracotta pots suck up an amazing amount of water) so, if you can, water them thoroughly and then plant them out in the ground with plenty of well-rotted manure worked into the soil and much watering before and after.

Star jasmine are not reliably hardy and will require good quality loam based compost such as John Innes no 3 mixed with up to 20% MPC to aid water retention.

Thank you for your helpful comments ….. I intend to save the present occupants as you suggest. But does anyone have suggestions for more suitable replacements?

Some of the early flowering clematis which prefer poorer, drier soil would be better.
Alternatively, some shrubs or grasses might be better depending on your preferences.
Another good solution is to get a few plastic pots which will fit neatly inside the smart ones, and plant them up with seasonal specimens to swap around - bulbs for spring, an evergreen of some kind for winter, and annuals or perennials for summer. Sweet peas would give you an annual climber, or Ipomeas.

Thank you, Fairygirl. Your comments are most useful … because all the pots are in front of trellis,  I think I’ve been restricting my thoughts to plants which need a lot of support and tying in. But I could consider some tall perennials, couldn’t I? There must be some which would suit this position. Thanks again.

Absolutely 
Sometimes it's a question of just seeing the problem in a different way. Have a look at some of the taller perennials though - I passed garden last year which had a selection of pots at the front door, and one had Crocosmia in it. Not a plant I'd have thought of having in a pot, but they looked terrific. 
Astrantias could be good too, as long as they don't get dried out. Many are quite architectural. 
The eaves of the house will prevent rain water getting in, so it's a question of whether you pick things which will manage the drier conditions, or whether you're prepared to put the time in with watering etc. Those early clematis will certainly do well though - alpinas, macropetalas, koreans etc

The common orange one [Montbretia] is best kept contained. It's highly invasive. 
The named varieties are much better behaved. I've got Emily McKenzie just now, and I might take some of it to keep potted, to sit with other orange/yellow plants etc.
The ones I saw were one of the yellower varieties, and were with pots of other toning colours. It was very smart. 

Lucifer would probably make a good pot specimen as long as it had adequate care, and a big enough pot. It's a very striking plant.
