19 Exterior Window Flower Box Inspirations That Add Instant Color

When you drive by a house, the windows along the facade grab attention first, especially if the siding feels a bit flat.

Exterior flower boxes fill that space with color at eye level and pull the whole front together.

I added a few to my own entry side last spring, and they made the brick look less stark from the street.

Good ones hug the window trim and nod to the roofline so the house reads more balanced.

A couple in this set might suit your setup worth sketching out for next season.

Window Flower Boxes on Dark Brick Facades

Flower boxes like these work great on older brick houses with dark walls. The purple salvia and yellow marigolds stand out sharp against the blackish bricks and shutters. It pulls the eyes right to the windows and makes the front feel more alive. Simple as that.

Window Boxes on White Stucco

White stucco walls give houses that clean, timeless feel. But they can look a little bare on their own. Flower boxes tucked under the windows fix that quick. In this setup, red and pink geraniums trail out from simple terracotta boxes. The color pops right against the smooth white surface and makes the whole side of the house feel alive.

These work best on older Mediterranean or Spanish-style homes where the arches already set a pretty frame. Hang matching pots at ground level to tie it together. Geraniums hold up in sun and don’t need much fuss. Just water regular and trim spent blooms to keep the show going all season.

Window Flower Boxes on Shingle Cottages
