Try the Tree Forum, where people focus on tree choices.

You might want to also check out "Teddy Bear" southern magnolia, a dwarf form which will fit in a 10 x 10 ft space.

The Teddy Bear Magnolia can be limbed up to allow navigation underneath. Similar to the rendering below, which would also work.

Thanks for the feedback, would Taylor junipiters do the job?

If the fence is removed to the right, I will have a 30 strip 2 foot wide to plant a privacy screen. Would American Pillar Arborvitae be a good fit.

2 ft. wide is narrow for something 15 ft. tall, that branches all the way to the ground - you are wanting that the plants be more than 6 times as tall as they are wide. And that's assuming they can be allowed to grow right up to the edges of the beds on each side. So even if you get columnar conifers to work for a time you will be looking at having to start shearing your living wall every spring at some point. With the stage soon coming where the attempt to stop their sideways expansion with this procedure results in stubs and bareness developing. A condition that has to be resolved by going through and doing some selective cutting back, with hand shears or small loppers.

I have attached another photo, any suggestions of what can be planted to block neighbors view into yard. About 4+1/2 feet between fence and garage. White pine, American pillar arborvitae? Thanks

Some kind of bamboo? Ah, Gardengal already suggested it.

Beavis77. Did you end up going with the American pillar Arborvitaes?
