I don't think it's long enough for a second lamp of this thickness and wouldn't recommend a wine rack; it's too large. Take a look at console tables on Houzz for ideas, but I think you just need some layering of different proportions. Two hurrican lamps and some books or an orchid is a nice idea.

A larger lamp (instead of the one you have), a small plant (take advantage of all that sun!) and a tray. In the tray you can change out items with the seasons. A small stack of books, large seashell, holiday treasure, family momento, framed photograph, etc. Pretty!

Why not bring the outside in. a large glass or pottery decorated bowl filled with moss balls
