Advice on potted trees for shade outside a north-facing conservatory

[catspyjamas1]

Hello. Looking for some gardening advice. I am not very experienced!

I have a conservatory that backs out onto a patio. I would like to have some plants / trees in pots on the exterior of the conservatory to provide shade and help reduce solar gain. FYI, I have already had the roof replaced with proper insulation, tiles etc.

The exterior wall is shaded in the morning until about 1-2pm when it's full sun until sunset.

I would like the plants / trees to not exceed 6-7ft and will be fine to prune, maintain etc. I absolutely do not want bamboo and would ideally like native British plants.

I have shortlisted hazel, hornbeam and common dogwood. Wondering if anyone more experienced can advise

A) would these work or anything else be better?
B) any other recommendation beyond small trees to consider?

I plan to plant in Autumn.

Thank you for useful advice!

I have a weeping Cersis and it has heart shaped leaves. It’s in a large 60cm pot. It’s settled well

I also have a magnolia for partial shade there are three varieties but this is my first year for that

I highly recommend a pot stand with wheels to be able to move the large heavy pots. This allows cleaning and to adjust the light exposure/sheltering at different times of year.

I presume you want something with summer foliage, to shade in summer but to allow more light in winter.

I know it's not what you asked, but I guessed that Bunny Guinness would probably have a video on something like this - and she did, 7 days ago!
Here's the video. If you fast forward to 7 minutes in, she has some other ideas for planting.
This is her video on baseless pots. Oooh, I hadn't realised that the one video was a 5 year follow-on from the other. Nice to see a before and after!

Have you considered multi-stemmed trees? By definition, they are pruned so you can control / shape them at will.
Google and you will find suggestions. Many are foreign trees but there are natives like birch, spindle, dogwood, sambucus nigra, etc.

Maybe put up a trellis or pergola and grow a grapevine up it. That will like the afternoon sun in summer, and you could even get some grapes to ripen.

You haven't watched Bunny's video that I linked to, have you.

That's such a good recommendation about the wheels! Thanks you.

Thanks for the videos above and other advice, will continue my research. Appreciate it!

You will need a big pot for a tree to be 6-7 ft. It won’t have much root space in a conventional pot. I have a slow and low growing acer. It has very dark leaves and is a star. It’s a Garnet dwarf I think but I’ve had it for 20 years!
