Climber for coverage

[Grandmarnier]

Hi, hoping someone can give me a few pointers. I have a trellis on both sides of my garden which borders the neighbours gardens. At the moment it feels very over looked and we lack privacy. So I'd like to put a fast growing climber to cover the trellis. The area needing to be covered on either side is about 3 metres long x 1.5 metres high. (The trellis's sit on top of lowish fences) I can only use pots though, so can't use anything which won't be happy in a pot. Oh and I'm seriously not green fingered so something which likes neglect would be best!!!

Does anyone have any ideas? I'd be really grateful for any suggestions. Thanks

It woudld help to now whether they are shady or sunny.

Clematis can do well in pots - some are evergreen so will give you privacy in the winter too. Choose a middle size one - not clematis montana which wouldn't be happy in a pot.

There's some evergreen jasmine that work in a pot and a climbing hydrangea if its shady.

Climbers in pots need tall pots - and you need to water and feed them - I'd use a mix of multi purpose compost and JOhn Innes no. 2. Put in slow release feed capsules and replace the top layer of compost every year.

Another thing that could work well is a tree in a pot - if its a big enough pot then a tree can do well for a few years.

Thank you for the suggestions! It's very sunny - sorry should have said that.
I like the idea of an evergreen clematis.
