Your window boxes don’t have to check out when summer does. Swap in richly colored flowers, textured foliage, ornamental grasses, and a few gourds, and they’ll become one of the best-looking spots in your fall garden. Autumn hands you a built-in palette too — pumpkin orange, wheat gold, burgundy, plum, deep green — so almost any combination from this list will look intentional.
The trick to a fall window box that actually works is layering height. Start with upright “thrillers” in back, build rounded “filler” plants through the middle, then let vines or trailing flowers spill over the front edge. Use the 12 combinations below as a starting point, and adjust plant choices for your light, climate, and box size. If your thinking about getting ahead on the season, you may want to check out Christmas window box planters as well.
1. Fiery Celosia and Marigold Window Box
Flame-shaped red celosia plumes give this box real height and unmistakable autumn character, backing up dense clusters of orange, gold, and red marigolds. The layered warm tones really pop against dark siding and simple cream trim.
Plant celosia toward the back, then fill the middle and front with marigolds — mix flower sizes so the display doesn’t read as too uniform. Both plants want full sun, and regular deadheading keeps the marigolds blooming right up until the cold sets in.

2. Yellow Daisies, Mums, and Ornamental Cabbage
This full, abundant box pairs cheerful yellow daisy blooms with burgundy and gold chrysanthemums. Ornamental cabbage rises through the center for bold shape and cooler purples and greens, while silvery trailing foliage softens the edge and balances out the heavier flowers.
Place ornamental cabbage at the back, mums are perfect planter pairs for fall, build rounded clusters along the front, and add daisies for height and movement. Tuck a silver trailer like dichondra near the center. It’s colorful without leaning on the usual orange-and-red fall cliché.
3. Dahlias, Rudbeckia, and Trailing Amaranth
Red and orange dahlias are the stars here, with yellow rudbeckia and other daisy-shaped blooms woven between them. Upright golden flower spikes tie the different heights together, silvery foliage adds contrast at the base, and long burgundy amaranth tassels finish it off in style.
This one needs a deep, well-supported box — dahlias and mature trailers get big. Go with compact dahlia varieties where you can, and stake or pinch back tall stems if your spot is windy. Let the amaranth cascade freely, trimming only if it starts hiding the container or plants beneath it.
4. Red Autumn Vines, Moss, and Sedum
You don’t need flowers when foliage does this much work. Red leaves that mimic Boston ivy or Virginia creeper glow overhead, while mosses and silvery sedum spread across the soil below — like a miniature woodland scene after the first cold snap.
The contrast between glossy leaves, feathery moss, and tightly packed sedum is what sells this look. Use a moisture-retentive mix for the moss but make sure the container still drains well. Since moss and sedum have different watering needs, tucking each into its own concealed pot makes upkeep much easier.
5. Bronze Mums and Bundled Wheat
One big bronze mum and a bundle of pale wheat — that’s it, and it works. The mum brings a broad mound of saturated color, the dried grain adds height and rustic texture, and burgundy vine foliage around the window ties it all together without crowding the box.
Easy to throw together fast: set one or two compact mums on one side, secure bundled wheat on the other. Anchor the dried stems deep so fall wind can’t yank them loose, then tuck in pinecones, seed heads, or twiggy branches to hide any gaps.
6. Nasturtiums, Mums, Marigolds, and Pumpkins
Rounded nasturtium leaves weave through orange marigolds and yellow-bronze mums here, and the mix of greens keeps the tightly packed flowers from feeling heavy. Above the box, a cluster of orange, cream, and pale green pumpkins spills onto the windowsill for a full harvest-display effect.
Set mums at the back corners, let nasturtiums wander through the middle and edges, and fill the gaps with compact marigolds. Keep pumpkins on the sill or another solid surface — never resting on stems — and check them for soft spots after rain.
7. Pumpkins, Celosia, Coleus, and Trailing Greenery
Small pumpkins nestle among red celosia, burgundy coleus, white heather-like blooms, and lush trailing greenery. The pumpkins act as focal points rather than afterthoughts because the surrounding foliage grounds them. Red, white, green, and orange make for a surprisingly sophisticated fall palette. Make use of those bigger pumpkins as well with these pumpkin planter ideas.
Start with coleus and celosia at the back, add flowering plants through the middle, then place your mini pumpkins last on flat or gently tilted spots where they’ll stay put. Trailing plants along the front hide the container and make everything look lush and established.
8. Orange Petunias and Burgundy Trailers
Petunias read as a summer plant, but orange and golden varieties transition into early fall beautifully. Their trumpet blooms glow against fresh green leaves, yellow flowers, and deep burgundy trailers — seasonal without a single pumpkin or straw bale in sight.
Keep feeding and deadheading as temps drop; healthy petunias can bloom well past what you’d expect before a hard frost. Protect the box during early cold snaps, clear faded blooms after wet weather, and let a burgundy trailer bridge the bright petunias with the darker tones around them.
9. Rudbeckia, Zinnias, Sedum, and Ferns
Golden rudbeckia with dark centers is the heart of this one, with taller orange zinnias rising behind it and red sedum anchoring both sides. Arching fern fronds fill the front for a cool green contrast beneath all that bright, daisy-shaped color.
Every layer here has its own shape: zinnias upright in back, sedum mounding at the sides, rudbeckia center stage, ferns along the front edge. Ferns want more consistent moisture than the flowering plants, so keep an eye on the root zone and don’t let it dry out completely.
10. Ornamental Grasses, Purple Salvia, and Autumn Vines
Tall ornamental grasses give this box the feel of a windswept fall meadow. Purple salvia spikes rise between the seed heads, violet heather spills over the front, and red-orange foliage rounds out a planting full of movement and texture.
Pick compact grasses that won’t overwhelm the window or block indoor light. Plant them in back, salvia between the clumps, heather low in front. Let the vines trail asymmetrically instead of trimming them straight — that relaxed shape is the whole point.
11. White Mums and Plume Grasses
A wide band of white chrysanthemums gives this one a clean, luminous foreground. Tall plume grasses and finer golden grasses add height behind them without feeling solid or heavy, and red vine foliage around the edges keeps the white-green-tan palette from going stark.
Bank several compact white mums along the front in an unbroken row, then vary grass heights behind them for a loose, airy silhouette. This restrained look is especially striking against dark containers — great for anyone who wants fall décor without going full orange.
12. Zinnias, Cordyline, Lantana, and Trailing Flowers
This one goes bold. Red zinnias and red-orange lantana form a dense flowering canopy punctuated by upright burgundy cordyline, a yellow dahlia adds a bright accent, and fine pink flowers with a glossy trailing vine tumble below the wooden planter.
Cordyline gives it vertical structure, zinnias and lantana fill the center, and trailing plants soften the bottom edge. Keep airflow good by removing damaged leaves and spent blooms, especially in damp weather, so the tightly planted box stays healthy through fall.
Final Thoughts
None of these window boxes need to be copied exactly — think of them as a menu of proven combinations to riff on. The common thread across all 12 is that layering trick: something upright in back, something full through the middle, something spilling over the front. Get that structure right and almost any autumn palette will look pulled-together.
If you’re starting from scratch, pick one plant you already love — a mum, a celosia, a trailing vine — and build outward from there using the thriller-filler-spiller framework. Your fall window box will look intentional, full, and ready to carry your curb appeal right up until the first hard frost.
