Please tell us where you're located (nearest big city & state), the approximate number of hours of sun this garden receives and the approximate dimensions of the space. Thanks!

Yeah......plant something!!

Seriously, visit a local retail garden center and see what they have that will be hardy for your climate, of an appropriate size and suited to your light conditions. Since we have no idea where you are, we can't get any more specific,

Lots of sun. In Arkansas

I'd place a decorative trellis with a vine against the fence and plant an evergreen groundcover in front of the trellis.

Yes I was thinking that! Like a jazmine or honeysuckle? Which side of fence? Next to the gate?

I'd place the trellis along the long side fence. You could use clematis, jasmine, honeysuckle - stay away from trumpet vine or Asian wisteria.

It looks like your plants will come back this summer. Sometimes abelia & loropetalum get off to a slow start.

Yes they are. The holly tree in the corner is gone though. I was wanting some height somewhere. Thought about another cypress or some kind. But I have one so close

Here are some ways to embellish the area:

Oh wow. What’s all the pink and purple flowers

They are astillbe, ice plant & agastache.

If I get a trellis to put on one side. How tall should it be. That’s a 6 foot fence. Does it need to be as tall as fence? Or will it keep climbing up

Clematis, jasmine and honeysuckle would all climb that fence without a trellis but they would go through to next door's side. If you use a trellis it needs to be the same height as the fence.

Some ideas
