To help fill your fall window boxes with the luscious textures and tones of the autumn season, use a variety of seasonal plants that will thrive in the cooler weeks of fall. Here are a list of the best fall flowers and right plants that you can mix and match to create stunning fall window box ideas that dazzle with colorful warmth.
Flowers & Bloomers Fall Window Box Ideas
- Chrysanthemums (Mums) — Mix in the classic fall staple.  Chrysanthemums or Mums are available in orange, yellow, burgundy, and white mums. They add lots of autumnal texture and color in one shot.
- Pansies — Mix mums in with pansies which are extremely cold-hardy and come in rich jewel tones perfect for autumn.
- Snapdragons — Add in snapdragons which tolerate cool temps and add vertical interest while acting as a thriller plant in center spots where taller plants can create a focal point.
- Marigolds — Bring in the rich warm orange and gold tones of marigolds which bloom well into fall.
Foliage & Texture Fall Flower Box Plants
- Ornamental Kale & Cabbage — adding ornamental cabbage and kale plants in stunning purple, white, and green rosettes will add character with plants that actually look better after a frost. They are frost-tolerant plants that tolerate cold temperatures for a perfect hardy cool weather window box.
- Sweet potato vine — Add sweet potato vine for trailing foliage in chartreuse or deep purple.  The vines are great for adding that “spiller” effect to fall planters.
- Dusty miller — silvery-gray foliage plant that contrasts beautifully with fall colors
Grasses & Fillers Fall Planter Ideas
- Ornamental grasses — Add wispy movement and texture with fountain grasses or purple fountain grass.  Grass plants bring in height and drama to the center of any container gardens or window box planters.
- Sedge — Sedge plants are low-growing, they stay green and tidy in cooler weather making them another great choice for a fall container garden.
Build Fall Window Boxes with Berries & Extras
-  Beautyberry — Purple berries add a pop of unexpected color and texture when paired with other fall plants like golden yellow flowers, or deep purple autumn foliage like coral bells.  Mix in maple leaf branches for added depth and warmth.
Alternatively, you could also tuck in artificial or faux red berry branches as well as colorful dried eucalyptus branches for instant color.
- Winterberry holly — A touch of bright red berry branches is very festive and nice transition into the winter months.Â
Small Pumpkins and Gourds Mix Fall Window Box Ideas
- Mini pumpkins — Little pumpkin varieties like ‘Jack Be Little’ or ‘Baby Boo’ (white) tuck perfectly into window boxes without overwhelming the space or the window frame.
- Small decorative gourds — Bumpy or smooth decorative gourds in mixed shapes and colors like yellow, green, and orange will add a whimsical touch while creating a textured and vibrant display for your flower boxes. You might also try small pumpkin branches to tuck in behind fall flowers for a central accent.
- Tiny hubbard or acorn squash — You can add deep green or steel blue tones with acorn squash which add unexpected color contrast.
- Dried or preserved gourds — Long-lasting and low-maintenance dried or preserved gourds are great for pairing with fresh plants like mums and kale that make excellent late autumn flowers.
- Trailing small gourds on vines — If space allows, a live gourd vine can be added and spilled beautifully over the front of a deep box for a truly festive, rustic, and elegant window box that will give the space a real fall makeover.
Alternatively, a maple vine with trailing fairy lights could be mounted overhead to frame your fall window box with added detail.
Fall window boxes are a wonderful way to embrace the season and add warmth and charm to any outdoor space.
By combining rich blooms like mums and pansies with textural elements like ornamental kale, trailing sweet potato vine, and whimsical mini pumpkins + gourds, you can create a display that feels both festive and elegant just in time for the fall season.
The best part is that many of these plants are incredibly resilient in cooler temperatures, meaning your window boxes will stay beautiful well into the fall season.
Whether you prefer a classic harvest palette of oranges and reds or a more unexpected mix of purples and silvers, there is truly no wrong way to style a fall window box. So gather your favorite seasonal picks, get planting, and bring a cozy autumnal magic to your windows this fall.
