When Halloween rolls around, fun costumes, creepy outdoor decorations, and carved pumpkins fill the streets of Seattle. From family trick-or-treating in Queen Anne to unique neighborhood parades, the whole city comes together to celebrate.
Beyond setting out props on the lawn, your landscape can help you create a mysterious atmosphere to mark this time of the year. Here are a few of our favorite Halloween garden ideas:
Set the Scene with Spooky Lights
Lighting can transform how your garden feels after dark. For Halloween, that means playing around with contrast, shadows, and colors to achieve that spooky look.
Cast Shadows with Garden Lights

Positioning garden lights at the base of trees, retaining walls, or other landscape features creates striking shadows and silhouettes. If you aim the light upwards and pair it with bare branches or fake cobwebs, you can create even more dramatic shapes to give your yard a creepy look.
Use Color Changing Lights
Color changing lights let you shift your landscape’s color palette for the occasion. For Halloween, that can mean trying out deep purples, oranges, and greens.
Outdoor Decorations

Before buying new decorations, look at what’s already in your yard. Fences, pergolas, and even trees can act as the backdrop for your Halloween garden ideas.
- Turn your pathway into a haunted experience. Adding pumpkins, flickering lanterns or other decorations can make your entry feel more interactive for trick-or-treaters.
- Wrap trees for texture. Hanging cobwebs from low branches or wrapping gauzy fabric around the trunk can give a mature tree the haunted look Halloween calls for.
- Use your fence as a backdrop. Cutouts like bats, witches or spiders stand out best against a clear, flat surface. You can take advantage of your fence to showcase these shapes.
- Make your pergola a centerpiece. Draping string lights or hanging skeletons can easily turn it into the focal point of your backyard.

Choose Plants with a Halloween Look
Some plants lean into the season on their own, with no decorations required. Their dark foliage, dramatic shape, or unusual color makes them a natural fit for the Halloween season. Here are three of our favorites:
Weeping Alaskan Cedar (Callitropsis nootkatensis 'Pendula')

This weeping tree has branches that look a bit ghostly and add a mysterious look to any garden, especially with uplights at night.
Black Diamond Crape Myrtle (Lagerstroemia indica)

This variety has deep purple (almost black) foliage with red flowers, giving it a gothic dark vibe. This unique look makes it stand out from the usual fall color palette.
Dark Purple Heuchera (Heuchera micrantha)

This perennial adds near black color at ground level, making it an option for lining paths or filling in around pumpkins and other decor.
Bring the Halloween Spirit to Your Yard
Preparing your garden for Halloween doesn’t always have to mean running to get new decorations. By combining lighting and plants with your existing hardscapes and only a few selected decorations, your yard can feel festive and ready for these October nights.
However you celebrate this year, we hope your garden feels spooky all season long!
