Recommendations for very tall screening plants suitable for large patio planters

[Julysunshineishere]

Can anyone recommend a very tall plant, growing to 8ft or more that can survive in a patio planter and used for screening purposes?

I've been advised by different garden centre staff that bamboo isn't recommended as too vigorous, and the container will break.

I've looked at elephant grasses but they only seem to grow to around the height of our 6ft fence.

I'm ideally needing something higher that will provide screening from neighbours.

Any suggestions would be appreciated!
I cannot plant anything in the ground sadly as the area is paved.

Thanks.

Could you get raised wooden planters with trellises attached so theyre already a good few feet off the ground for elephant grass or grow something quick up them? Honeysuckle? Clematis? Rambling rose? Or actually just attach trellises to the fence as an additional starting element to screen the neighbours

Thanks for suggestions. I love clematis and roses and have started growing some against a trellis, however I need something that will grow taller than the 6ft fence, as it is overlooked. I'm just not sure what will grow taller than the fence and will be happy in a container. I can't add trellis to the top as it will make the fence too high.

Having been thinking about the plants suggested and the height I need. I'm off to Google the height of obelisks...a very tall one in a planter with a rose or clematis and trellis on the fence might work.
Has anyone done this?

One thing you need to consider with a tall plant in a container is whether it could blow over in a high wind.

Whats on the floor concrete or paving slabs ( which can be removed). Im moving away from pots as tbey need more watering, im in The south though.

Yamadori- Yes, that is a concern. That's why I posted as I imagined large grasses etc that wouldn't be as heavy, but I'm no gardener, so was looking for suggestions.☺️
Casualuser- It's concrete so can't lift any paving, so needs to be pots.

I'm wondering if a wide metal archway to put the patio set under with the legs of it in two deep wooden planters with clematis over might be the way forward.

Agriframes have a very good range - might give you some ideas? https://www.agriframes.co.uk/collections/pergolas

Thanks for suggestion .

Clematis will drop its leaves in winter. Do you want year round screening? I would be considering something evergreen and keep in check with pruning. Perhaps conifer, red robin, laurel or holly.

Clematis Armandii is evergreen. I have a neighbour who has one growing up a wall to about 10 or more ft so I think that over an arch rooted in two very heavy planters is a great idea.

Thanks for the name of an evergreen clematis. Really helpful.

I’d get a pleached bay tree in a pot at least 80cm diameter and bigger if you can. With plenty of feed and water, it will grow well.

Pittosporum might work in a really large pot.

I too was going to suggest pleached trees.

I love pleached trees, I'm just cautious about my limited gardening experience and the cost of them! I wouldn't want to kill them.
I spoke with an on line tree supplier who suggested red robin pleached trees and securing them to the fence posts for stability, and planting in troughs with 150litres capacity. I know that they would look great, ideal for screening, it's just such a lot of money to loose if my skills aren't up to it.

luvaflatwhite I'm off to Google! Thanks for the suggestion.
parietal That's reassuring to hear.How often do you feed your trees?

evergreen jasmine (there are many kinds eg Trachelospermum jasminoides) gets dense and has glossy leaves year round, would be lovely on an arch

Literally came on to say this. I have a VERY narrow strip between my paving and my fence. No problems growing jasmine up my 6ft fence even with limited soil and water.

Red Robin is a nightmare as the leaves take an absolute age to compost down. My neighbours has struggled in the drought and lost 90% of its leaves. I agree with other posters about jasmine. Mine has flowered continuously since early July and the scent is wonderful.

From my experience, bamboo can be grown in large pots without cracking them but it doesn't grow as high as when it's planted in the ground.

I have one (don't know what type) that's in a large pot. I split it years ago and planted part in the ground, which has grown several feet higher than the potted section. And spead, but not too annoyingly.

The potted bamboo does blow over in high wind and is a bugger to keep watered in long dry weather. It's looking very scraggly at the moment.

I’ve just looked up tall grasses and this came up 1m-2.5m
Calamagrostis 'Karl Foerster'
Anyway I’m sure there are others -you might need to raise the pot to get the right height -they can be feathery but at least they do t catch the wind like a top heavy tree or shrub

Thanks for the plant recommendations. I do love jasmine too. I'm just trying to think of a way to get it higher than the 6ft fence without breaking planning laws though☺️

I've had a quote for a tall half pergola to run alongside the fence at 2.5m high, but the price was over 1k, far too much just for the structure, so I'm trying to find more cost effective solutions that suits my gardening skill level as well as my pocket!

Pruning a pleached tree could be an issue too, as the neighbours over the fence aren't the friendliest unfortunately, so I couldn't offer to go round and trim them. All would have to be done from our side of the fence.

A lot to think about, but thanks for the ideas, they are very helpful.

Thanks for the idea of grasses, I will look into that one. We did try to grow elephant grass a few years ago, no luck, didn't get even a foot tall! I'm not sure what happened there but wholly unsuccessful! A plant that's a decent, established size is the way forward I think!

If you keep on top of watering them cherry laurel manages in a large pot. They grow quickly and are dense. Not expensive either - always advertised on Facebook marketplace. I got 3-4 foot plants and they've doubled in height in around 2 years. You will need to prune each year because they want to be large trees.
