White plaster Christmas trees are featured in the breakfast room designed by Meredith McBrearty Interiors for the 2017 Home for the Holidays Designer Showhouse in Atlanta. The trees are on an iconic white Knoll Saarinen tulip table.
If the spatial limitations of your own front porch don't allow for life-size Christmas trees, instead create a similar look with a grouping of tabletop trees ranging in heights and colors. This collected look will seem a bit more eclectic and gathered over time. If you simply incorporate one tree that lights up, it should be enough to cast a soft glow on the others.
