Climber advice

Many clematis will be fine on pots, and there are varieties for every aspect, so that might be suitable. The early ones grow from the existing framework, so that would be better than the late ones which get cut back each year, as you'd still have some cover through the dormant period. Many of them prefer a drier environment too, so containers are ideal for that.
The alpinas, in particular, will do well and can cover a good area once established, and I have a macropetala [Lemon Dream] which is also very vigorous, especially this year as the weather has been so mild, so much more vigorous than normal!
Mine are all in raised beds, to keep them drier, and one is in a tiny space, although it can get down into the ground below, but that isn't particularly inspiring soil there! It's Clem alpina Constance and covers a decent area.

Most of those early ones will be perfectly fine in Fife too. The koreanas are iffy here - I can't keep them alive no matter how good a site I find for them. Too wet

 

Hi @DaifraeFife I’ve got 4 clematis growing in pots on my patio and all are doing really well. I took advice from a clematis nursery, they said to plant in a large pot, and to water regularly and feed weekly in the growing season and it’s worked for mine.

I’ve got Koreana Amber in the front pot which has grown over 10 feet high, it doesn’t need pruning so over winter you’ve still got the framework for cover, it flowers from April and I’m still getting flowers now. I’m really pleased with this clematis and it receives lots of compliments from visitors.
