Indiana Nature Guide: December 2026
December brings winter to Indiana — short, gray days, the first lasting snow, and the lakes and ponds beginning to freeze. The bird feeders come into their own, the bald eagles concentrate on the open rivers, and the Christmas Bird Counts take to the field as the natural year quiets down to its hardy winter core.
What to look for this week
- Feeders are at their winter peak — northern cardinals, chickadees, tufted titmice, and juncos work the seed through the cold.
- The Quadrantid meteor shower peaks in a short, sharp burst around January 3; watch the northeast after midnight from a dark rural site.
- A planning week — order seeds early, especially short-season varieties for northern Indiana, before they sell out.
Birds This Month
December birding in Indiana centers on the feeder, the open water, and the long tradition of the Christmas Bird Count, when birders across the state tally the winter avifauna. At the feeders, northern cardinals blaze against the snow alongside black-capped and Carolina chickadees, tufted titmice, white-breasted nuthatches, dark-eyed juncos, American tree sparrows, and downy and hairy woodpeckers. Carolina wrens scold from the brush, and irruption years may bring pine siskins or red-breasted nuthatches to the suet.
On the rivers and below dams where the water stays open, bald eagles concentrate to fish, joined by common goldeneye, common mergansers, and gulls. The wetlands at Goose Pond and Muscatatuck hold wintering tundra swans, ducks, and geese until they freeze, and the grasslands host short-eared owls hunting at dusk and the occasional rough-legged hawk. Most of the sandhill cranes have moved south, though some linger at Jasper-Pulaski into early December in a mild year.
What's Blooming
Nothing blooms outdoors in an Indiana December — the ground is frozen and snow-covered, and the next wildflowers are three months away. The dormant landscape offers color in its fruit and structure instead: the brilliant scarlet of winterberry holly glowing against snow in the wet thickets, the red berries and glossy leaves of American holly in the southern woods, the blue fruit of eastern redcedar, the orange-and-red of bittersweet twining the fencerows, and the bright red stems of red-osier dogwood along the shorelines.
The tan, rattling seed heads of purple coneflower, black-eyed Susan, and the prairie grasses stand through the drifts, holding both winter beauty and seed for the finches and juncos. Indoors, this is the season of amaryllis, poinsettias, Christmas cactus, and forced paperwhites on the windowsill — the bloom moves inside for the holidays — and the year's first seed catalogs arrive to start the long winter dreaming for next year's garden.
Garden This Month
December gardening in Indiana happens mostly indoors and on the calendar. The outdoor beds are frozen and dormant statewide, so the active tasks are protective and reflective: confirm that mulch is insulating perennials, garlic, strawberries, and fall plantings against the freeze-thaw cycles that heave and kill crowns, and check that tree wraps and fencing are guarding young trunks from rabbits, deer, and sunscald through the hungry winter months.
Leave snow where it falls over the beds — it's the best insulation a Hoosier garden gets — but gently knock heavy, wet snow off evergreens, arborvitae, and shrubs to prevent breakage. Keep the bird feeders full and a heated birdbath open if you can. Otherwise, this is the planning season: order seeds early (especially short-season varieties for the north), sketch next year's beds, clean and sharpen tools, and force a pot of paperwhites or an amaryllis for indoor color while the garden sleeps.
Zone 5b (northern Indiana & the lake region): the garden is locked down under frozen ground and lake-effect snow — leave that snow as insulation over perennials, knock heavy snow off evergreens, and turn to planning and seed catalogs at the kitchen table.
Zone 6a (central Indiana): the beds are dormant. Confirm mulch is protecting bulbs and tender perennials, keep feeding the birds, and use the down time to clean and sharpen tools and plan next year's garden.
Zone 6b (the southern Ohio River counties): the mildest corner is still effectively shut down, but the hardiest greens under cover may yield a last cutting. Focus on mulch checks, dormant-season planning, and pruning fruit trees on the occasional mild, dry day.
What's at the Farmers Market
December markets are the indoor winter markets — Indianapolis, Bloomington, Fort Wayne, and others — and the holiday-and-storage harvest. The durable crops carry the season: winter squash, sweet potatoes, potatoes, onions, garlic, carrots, beets, turnips, parsnips, cabbage, and Brussels sprouts, plus the cold-sweetened kale and collards and the last of the cold-stored Indiana apples. The heated hoop houses supply fresh spinach, mâche, and microgreens.
The holiday market adds its own character: locally grown Christmas trees, wreaths, and evergreen greenery (pine, fir, and spruce from Indiana tree farms), plus honey, maple syrup, jarred preserves, baked goods, and eggs for the holiday table. Look too for southern Indiana persimmon pulp, sold frozen for the traditional Hoosier persimmon pudding. Store roots cool and humid, squash and onions cool and dry, apples cold, and keep a fresh-cut tree's stand topped with water to hold its needles through the holidays.
Night Sky This Month
December gives Indiana its longest nights of the year, around the winter solstice, and the cold, dry air makes for superb, if frigid, stargazing. The brilliant winter sky is back in force: Orion climbs the southeast in the evening with the Orion Nebula glowing in his sword, the Pleiades and orange Taurus ride above him, and the Winter Hexagon of bright stars — Sirius, Procyon, Pollux, Capella, Aldebaran, and Rigel — sprawls across the sky as the night wears on.
The headline is the Geminid meteor shower, which peaks around December 14 and is the best meteor shower of the year — dozens of bright, slow meteors an hour radiating from Gemini, well placed all night and easily worth braving the cold from a dark site like the Hoosier National Forest or Goose Pond. The minor Ursids follow near the solstice. The printable Indiana night-sky guide lists this year's exact Geminid peak timing, Moon interference, and planet positions for your part of the state.
Butterflies & Pollinators
There are no butterflies on the wing in an Indiana December — the cold and snow have sealed the season completely. The year's butterflies are all in their hidden, dormant winter forms, scattered through the frozen landscape and waiting out the cold. The monarchs are far to the south, clustered by the millions in the oyamel fir forests of central Mexico, where the whole eastern population overwinters. The species that stay in Indiana are tucked away in their various overwintering stages.
The adult-overwintering mourning cloaks, eastern commas, and question marks are wedged behind loose bark and in woodpiles and sheds, their bodies loaded with natural antifreeze that lets them survive being frozen solid. The swallowtails hang as chrysalises on sheltered stems, the fritillaries wait as tiny dormant caterpillars in the leaf litter, and countless others persist as eggs glued to twigs and bark. This is the season to plan and order for a butterfly garden — native milkweed for monarchs and a long succession of nectar plants — so it's ready when the first mourning cloak flies again in late winter.
Trees This Month
Indiana's trees are fully dormant in December, and winter is when their structure and the conifers stand out. The bare deciduous crowns reveal their identities by silhouette and bark: the unmistakable white upper limbs of the American sycamore along the rivers, the shaggy plates of shagbark hickory, the smooth gray trunk of American beech holding its bleached, papery leaves, and the corky-ridged bark of hackberry. Young oaks, beeches, and ironwood rattle their tan marcescent leaves through the winter wind.
The native evergreens hold the only green and shape the winter landscape — eastern redcedar dark in the old fields and fencerows, white pine in plantings and windbreaks, and the berry-laden American holly in the southern woods, a favorite for holiday greenery. The persistent winter fruit feeds the wildlife: crabapples, hawthorns, sumac drupes, and the seed of the tulip tree, ash, and maple, drifting down onto the snow for the finches, cardinals, and waxwings that work the bare branches through the cold.
