Or mau be Should I add pampas instead of flowers .

IMO nothing fake ever . Also hang the art sxs it never works staggered .Maybe a small table so that the vase blocks the view of the busy wall unit.

Thank you , but what is sx, I have other real plant,but this just wanted to get one fake . May be a small side table undernesth the planter. I might remove it all together

I agree, nothing between the columns. Let the space breathe.

Also, Patricia, I agree that fake is not good but (alas!) for some of us it has to do. I have three cats who will eat anything living so I am faced with either the plants killing the cats or the cats killing the plants. Neither is acceptable to me. So while I have a lovely and thriving porch garden the inside of my home hosts a few faux plants and flowers. I wish it could be otherwise but it simply cannot.

Another vote for nothing between the columns.

The columns are an odd layout choice, so I would not draw any attention to them.

Agree no vase. Can your sectional be moved down towards fireplace a bit, lined up with the next pillar and perhaps a console behind it will fill in/offset the odd space as well as pillars visually from all directions.

sorry that was side by side missed an x . I also think maybe take a pic with nothing there and see if that really is the answer . We had cats for years they never ate my plants or flowers so i guess I was just lucky as we always had both all the time. The idea of opening that space behind the sectional sounds like a good idea but we need to see that whole space .From what I see the shelving unit is not good but again I have no idea of the whole space ,

A floor vase in that location is really not required. I would remove it.

I would also reposition the wall decor.
