Help on what to plan on retaining wall (NJ)

I have a 75' retaining wall at the rear of my yard. I am going to dig the mulch out and replace with stone and plant new trees. Here is a picture of what the last owner left us (don't mind the homes behind, you get the idea, I stitched together a few pictures and it didn't do a great job).

I may leave the plum trees on the ends but will remove the juniper and the dead bushes. They are about 10' tall and growing nice. I want something that will grow at least 12-15' to block the homes behind us, but not get too tall so it makes the yard like a "prison." Also want something low maint. that looks nice (color would be nice). I was thinking of these two options:

A solid wall of Emerald Green Arborvitae. They would start at 6' tall and grow from there. I would need a lot of trees, every 3-4 feet.

or

Put a 6' solid vinyl fence up, and plant more plum and some pear trees on the wall about every 10-12 feet. Eventually they will make a solid wall and add some color in the spring. The only issue is that I don't want anything too wide because it will extend too far over the wall into the grassy area of our yard.

My goodness, is New Jersey really Hardiness zone 7?

menace73, my vote is for a mixture and start with small trees and your idea of a bit of a vinyl fence.

You can put up a trellis and let some vines climb it. I know nothing about vines BTW.

Space in some variety of trees. All of one type is inviting trouble on a large scale and things will look weird if one dies and you have a gap.

Do you own enough of the land above the wall to stagger the planting also? Red and yellow barked Japanese maples in front of some evergreens are something I have wanted to try. Them spreading red twig dogwood shrubs have done me well also.

Arborvitae come in a hundred cultivars. Mix in a few. I am somewhat concerned about their eventual size being right on a retaining wall. How many feet back can you plant them?

Thanks for the response. I only own about 4' beyond the wall, so if I put a fence up, I only have 4' to work with between it and the edge of the wall.

I would have to agree with Toronado here. A misture of dwarf conifers (some blue, some green, maybe a yellow one here and there). Then perhaps a red weeping Japanese maple such as Red Dragon. The blues/greens/yellows/reds would really pop and be the center of attention. See the link below in the conifers forum

I wouldn't do a solid row of green emeralds. I'm just not a fan of them. Keep in mind trees never stop growing. When you see a size of like 6' tall, that's usually what it will be in 10 years. In 20 years it would be 12', etc. Eventually destroying that retaining wall.

How about pink pussy willows? Maybe a bushier cultivar?

@tornado - Yes, much of NJ is 7. There are probably a few places in the far south that are 8. Some places in the NW are 6 probably.
