Climbers for beginners - one for a container?

[TheTurnOfTheScrew]

I have a teeny, north-facing courtyard. I have two slightly grim looking fences that I'd like to prettify, so the outside space looks a little more garden and a little less prison exercise areal. I have no clue where to start.

one fence is south facing at the end of the garden so gets full sun in summer and partial in winter. This one does have the only diggable bit of garden in front of it, so I can plant into the ground.

the second fence is east facing, nearer the house.It probably only gets decent sun for 6 months of the year, and at best a hour or two's morning sun the rest of the time, with full shade in winter. It's also on concrete, so whatever goes there would need to be in a container.

Plants for both spots would ideally be pretty robust, as I am legendary for killing things.

Potato vine is very tough and mine romps away on a north-facing fence (prettier than its name). It is toxic if eaten so maybe not with toddlers?

On the sunny side I have jasmine, honeysuckle and a passionflower

If you want to try something annual (so fairly low risk and cheap) then you could do Spanish flag (from seed) or sweet peas (from seed or seedlings are not expensive) or morning glory (from seed, but it is bindweed family)

I have a passion flower on a North-East wall and it DOES very well. I largely ignore it too, so doesn't need much care.

Don't know why autocorrect made "does" capitals there. Sorry

Could I add a question on to yours OP? How big does the container need to be for these plants?

The bigger the container the more growth you get totallyyesno. So go as big as you can if you want plenty of growth.

My mum has a 14 year old clematis in a pot that's about 60cm diameter and 80cm depth. Just this year we've taken it out to strip away some roots because the pot was 85% root with very little soil left. The plant in full bloom covers the back of her (south facing) 3-bed detached house. It's massive.

Clematis has plants to suit every part of the garden. Annual climbers that are easy to grow are black eyed Susan and sweet peas.

Thank you all so much. I want something that will cover the eyesores for much of the year so the annuals might be less suitable. I will have a good look at all the recommendations, and kit myself out with some trellis. Are there particular clematis varieties I should be looking for (ie any idiot-proof ones)?

Clematis Montana is very easy but it will lose its leaves in the winter. If you want cover all year you need an evergreen. Things like a variegated ivy or jasmine. There is an evergreen clematis but I forget it's name. For the shady side an ivy would be better. You could also try a climbing hydrangea or a passionflower. Also a lot depends on how much space you have for the plant to grow out into the garden, some will grow out into the garden as well as along the fence.

Star jasmine would be lovely in a pot - shiny evergreen leaves and beautifully scented white flowers in spring. You'd need to be disciplined about tying it in but that should be easy if it's in a container. I have one that's gone a bit wild behind another plant, but I still love it.
