Discover botanical garden displays, Christmas traditions, winter landscapes, and seasonal celebrations throughout the United States in December 2026.
December brings a special kind of beauty to America's gardens. Although much of the country has settled into winter dormancy, botanical gardens, arboretums, and historic landscapes come alive with sparkling lights, festive greenery, colorful flowers, and celebrations of the natural world.
From the magnificent conservatories of Pennsylvania to the illuminated gardens of Georgia, December offers opportunities to enjoy horticulture in an entirely different light. Some events celebrate Christmas traditions that have delighted generations, while others invite visitors to discover the quiet beauty of winter landscapes.

Beyond the Lights: Other Ways to Enjoy Gardens in December
Although illuminated gardens dominate many holiday calendars, December also provides opportunities for quieter horticultural activities.
Holiday Wreath-Making Workshops
Many botanical gardens, garden clubs, and community organizations offer workshops devoted to making wreaths and seasonal decorations.
Participants may work with fresh evergreens, magnolia leaves, pinecones, berries, and other natural materials.
These workshops provide useful ideas for decorating homes with greenery gathered from the garden.
Traditional wreath-making is a particularly satisfying craft because it combines horticulture with the pleasure of creating something beautiful by hand.
Winter Plant Walks
December is an excellent month to study the structure of trees and shrubs.
Without leaves to obscure their branches, deciduous trees reveal their natural shapes.
Look for the graceful branching of dogwoods, the distinctive bark of river birches, and the striking silhouettes of mature oaks.
Winter walks also offer opportunities to observe evergreen plants, ornamental grasses, berries, and seedheads that provide food and shelter for wildlife.
Poinsettia and Conservatory Exhibitions
Public conservatories are especially inviting during December.
While outdoor gardens rest, greenhouses remain filled with tropical foliage, flowering plants, and seasonal displays.
Poinsettias naturally receive much attention during the Christmas season, but visitors may also discover orchids, bromeliads, cyclamen, and other plants that bring color indoors.
These exhibitions can provide inspiration for winter houseplant collections.
Garden Club Christmas Programs
Local garden clubs often organize December programs devoted to holiday floral design, natural decorations, and seasonal entertaining.
Some clubs also sponsor decorated-home tours, greenery sales, and community beautification projects.
Such gatherings preserve a valuable tradition of sharing gardening knowledge and encouraging neighbors to take pride in their surroundings.
Check local garden club calendars, county Extension offices, and public garden websites for events in your area.
December Gardening: There's Still Work to Be Done
Attending garden events is enjoyable, but December also offers opportunities to improve your own landscape.
In much of the South, winter is an excellent season for planting dormant trees and shrubs. Cooler temperatures and generally adequate moisture help newly planted specimens establish roots before summer heat returns.
Gardeners in colder regions can concentrate on protecting tender plants, inspecting winter mulch, maintaining tools, and planning spring projects.
December is also a good time to:
- Plant spring-flowering bulbs where soil conditions and chilling requirements permit.
- Protect vulnerable shrubs from winter winds and drying conditions.
- Clean and sharpen pruning tools.
- Inspect trees for damaged or diseased branches.
- Provide fresh water and appropriate food for winter birds.
- Plan new garden beds and landscape improvements.
- Enjoy the beauty of evergreens, ornamental grasses, and winter berries.
Remember that gardening calendars vary considerably across the country. What is suitable for coastal Georgia may be entirely inappropriate for northern Minnesota.
Always consider your local climate, soil conditions, and seasonal weather before undertaking major garden work.
Celebrate the Season in the Garden
December reminds us that a garden's beauty is not confined to spring blossoms or summer abundance.
There is beauty in bare branches against a winter sky, in the fragrance of freshly cut cedar, in bright holly berries, and in the warm glow of Christmas lights reflected on evergreen leaves.
America's botanical gardens and arboretums preserve these seasonal pleasures while introducing visitors to the remarkable diversity of the plant kingdom.
Whether you attend a grand Christmas exhibition, participate in a wreath-making workshop, or simply take a quiet walk through your own garden, make time to appreciate the landscape this December.
The garden may be resting, but its beauty has not disappeared. It has merely changed its dress for the season.
From all of us at GoGardenNow, we wish you a joyful Christmas season and many happy hours in the garden.
