I love decorating window boxes for fall because they add so much color without taking over the whole outside of your home. Even one box filled with mums, grasses, and a few tiny pumpkins can make a window feel ready for the season.
You also don’t need to make everything perfectly even. I actually like fall window boxes better when branches lean a little, vines trail over the edge, and the colors feel naturally mixed.
If you’re not sure where to begin, choose two or three fall colors you love and build from there. These 11 fall window box ideas give you plenty of different looks to try.
1. Mums and Mini Pumpkins
I love starting with mums because they instantly make a window box look like fall. I’d mix golden yellow and burnt-orange mums, then tuck a few cream and orange mini pumpkins between the flowers.
Add some trailing greenery around the edges so the arrangement doesn’t feel too stiff. A weathered wood window box looks especially pretty here because all those warm fall colors stand out against it.
2. Rustic Window Box With Dried Grasses
Dried grasses are perfect when you want something a little more rustic. I’d use tall wheat-colored grasses toward the back, then fill the front with rust mums and soft green foliage.
A few dried seed heads and small branches can add even more texture. I think this looks best in an aged wood box with plenty of natural grain showing.
3. Burgundy and Plum Fall Window Box
Sometimes I want fall colors that feel deeper than the usual orange and yellow. Burgundy mums, plum-colored foliage, and dark purple ornamental cabbage can make a window box feel rich without being too bright.
I’d soften those darker shades with cream flowers and a few pale green leaves. A little trailing ivy around the front edge keeps everything loose and natural.
4. Neutral Fall Window Box
If bright fall colors aren’t really your thing, I’d go with cream, beige, sage green, and soft brown. White mini pumpkins look so pretty tucked between ivory flowers and silvery-green foliage.
Add beige dried grasses and a little trailing greenery to give the box some height and movement. I especially love this look against white siding or weathered wood because it feels calm and cozy.
5. Fall Window Box With Ornamental Cabbage
Ornamental cabbage is one of my favorite plants for a fall window box because those big layered leaves add so much texture. I’d mix pale green and purple cabbage with rust-colored mums and smaller cream flowers.
Let a few ivy vines trail over the front, then tuck tiny pumpkins into any open spots. You don’t need many because the cabbage already gives the arrangement plenty of fullness.
6. Cottage Fall Window Box
For a cottage-style look, I like things to feel a little loose and overgrown. I’d fill a weathered wood box with small mums, trailing ivy, rosemary, soft grasses, and tiny white flowers.
Add a few miniature cream pumpkins between the plants for a simple fall touch. Let some of the greenery spill naturally over the sides instead of trimming everything into a perfect shape.
7. Orange and Rust Window Box
If you love classic fall color, this one is hard to beat. Burnt-orange mums, rusty red flowers, and warm copper leaves make the whole window feel extra cozy.
I’d add a few orange mini pumpkins and brown dried grasses to break up the flowers. Deep green trailing vines along the front help all those warm colors stand out even more.
8. Fall Window Box With Trailing Vines
Sometimes the prettiest part of a window box is what spills over the edge. I’d use trailing ivy and soft green vines across the front, then build height behind them with mums, grasses, and autumn foliage.
Mix in muted orange, cream, and burgundy flowers so the greenery doesn’t take over. I like letting the vines fall at slightly different lengths because it makes the box feel more natural.
9. Rustic Corn and Pumpkin Window Box
This one has more of a harvest feel, and I think it’s especially fun for a farmhouse-style exterior. I’d use small dried corn stalks or corn leaves toward the back with mini pumpkins nestled along the front.
Fill the spaces between them with golden mums, dried wheat, and a few muted green leaves. A rough wood window box really finishes the look without needing any extra decoration.
10. Deep Red Fall Window Box
Deep red can look so pretty outside when the leaves start changing. I’d mix dark red mums with burgundy foliage and a few rusty orange flowers for a warm layered look.
Add soft green leaves and trailing ivy so the darker colors don’t feel too heavy. If your house has cream or light-colored siding, I think these rich reds will stand out beautifully.
11. Late Fall Evergreen Window Box
When the weather gets colder, I like switching some of the flowers for greenery that can carry the box toward winter. Pine branches, cedar, and other evergreen clippings make a beautiful base for a late fall arrangement.
I’d tuck in a few cream mini pumpkins, dried grasses, brown seed heads, and small burgundy leaves to keep it feeling like autumn. Once fall is over, you can simply remove the pumpkins and keep much of the greenery for winter.
You really don’t need a huge window box to make a pretty fall display. A few plants, some seasonal clippings, and one or two little pumpkins can be enough to make the outside of your home feel warmer.
I’d have fun with it and let the arrangement change as the season goes on. Add what you find, remove anything that’s finished blooming, and enjoy making your window box feel a little more like you.
