Best trees for pots to add height in a small garden

[Clangershome]

Hello all, please could anyone give some ideas on trees for pots. We have a small garden. We would like some height over some of the fences to the neighbours. Looking for nice bushy height. Any ideas welcome

A fruit tree might work, apple or plum or fig. We have a few in pots from when we moved house, still haven’t decided where to plant them! They will all do better planted in the ground though.

Acers do well in pots and can be bushy, but they're not fast growers - around 15-30cm a year. So you could buy them not far off your ultimately desired height, but it gets quite expensive.

Bamboo would do the trick but it must be in a pot otherwise it can become invasive and out of control.

Bear in mind only evergreens will give you year round privacy, deciduous trees will be bare for a lot of the year.

We have an olive tree in a huge pot - evergreen, likes a sheltered spot in sun, loves dry conditions of pots. Needs a little prune once a year before frosts start and grows little olives. Slow grower so get a big one.

We also have Chinese redbud (cercis chinensis) in a tub. It is stunning - definitely the showstopper in our garden. We do have that in a wooden tub and I suspect it has broken through the bottom and rooted in the soil as it is growing so successfully

Edit.
Misread the OP and missed the bit about pots.☹️
