South Carolina Nature Guide: December 2026
December settles South Carolina into the mild Southern winter — the ACE Basin fills with wintering waterfowl, Christmas Bird Counts tally the season's birds, the Lowcountry holds its evergreen green, the markets center on collards and citrus from the coast, and the long, clear nights bring the brilliant winter sky and the Geminid meteors.
What to look for this week
- Tundra Swans and rafts of ducks crowd the ACE Basin impoundments at their winter peak, while Lowcountry Christmas Bird Counts wrap up across the state.
- The Quadrantid meteor shower peaks in a short, sharp burst around January 3 — best after midnight from a dark Upstate ridge at Caesars Head or the unlit ACE Basin marshes.
- A planning week in the cold Upstate, but Lowcountry cold frames keep collards and kale growing — order seeds early before favorites sell out.
Birds This Month
December is full winter birding in South Carolina, the season of the Christmas Bird Counts that tally the wintering flocks. The ACE Basin impoundments and Lowcountry refuges hold their waterfowl at high numbers — Northern Pintail, American Wigeon, Green-winged Teal, Gadwall, Ring-necked Duck, Northern Shoveler, Redhead, and Tundra Swan — watched over by wintering Bald Eagles and Northern Harriers.
The salt marshes hold Saltmarsh, Nelson's, and Seaside Sparrows, rails, and Marsh Wrens, and the fields and woods are full of wintering White-throated and Savannah Sparrows, Yellow-rumped Warblers, Eastern Phoebes, kinglets, and Dark-eyed Juncos. At Huntington Beach State Park, the premier winter site, the lagoon and jetty hold loons, Northern Gannets, Red-breasted Mergansers, Brown Pelicans, a few wintering Painted Buntings at the feeders, and the rarities that draw birders all winter. In the Sandhills longleaf, the Red-cockaded Woodpecker tends its cavity clusters, and the state bird, the loud Carolina Wren, sings through the mild days.
What's Blooming
December offers few wildflowers in South Carolina, but the mild coast keeps the garden alive while the Upstate sleeps. The fall-blooming sasanqua camellias give way to the first winter (japonica) camellias across the Lowcountry and Midlands — the flowers Charleston's old gardens were built around — and the season's pansies, violas, snapdragons, and chrysanthemums carry color through the cool weather. The very first yellow jessamine, the state flower, can open on a warm coastal day by month's end.
In the wild, structure and evergreen color hold the month. The red berries of American and yaupon holly, possumhaw, and the brilliant purple beautyberry light the swamp edges and old fields, the glossy mats of partridgeberry and Christmas fern keep green on Piedmont slopes, and the dark seed-heads of goldenrod, coneflower, and black-eyed Susan and the rusty broomsedge stand in the winter fields. Along the coast the silvered sweetgrass and the evergreen wax myrtle, live oak, and cabbage palmetto keep the Lowcountry green.
Garden This Month
December is a quiet but still-active month in South Carolina's mild-winter gardens, far from the frozen North. Across the Lowcountry and much of the Midlands the cool-season garden keeps producing — collards (sweetest now for the holiday table), kale, mustard greens, spinach, lettuce, cabbage, broccoli, carrots, and turnips grow on under row covers and cold frames, sweetened by the frosts. In the colder Upstate, freezes are the rule and the garden mostly sleeps.
Protect cold frames and tender plants on freeze nights, mulch garlic, strawberries, and perennial beds, and drain and store hoses before hard freezes. Prune dormant apple, peach, and pear trees and muscadine grapes on mild dry days. Plant any remaining spring bulbs in the warm coast, and start onions, leeks, and the earliest cabbage and broccoli indoors under lights late in the month. This is also the planning season — review what worked, sketch crop rotations, and order seed early, especially the warm-season varieties the long Southern summer rewards. Watch for deer browsing in lean weeks.
Zone 7b (Upstate & foothills): the coldest gardening of the state, with freezes the rule. Protect cold frames of greens, mulch garlic and perennial beds deeply, prune dormant fruit trees on mild dry days, and plan and order seed for spring.
Zone 8a (Midlands & Sandhills): mostly dormant but mild. Harvest frost-sweetened collards, kale, and roots under row cover, prune muscadines and fruit trees, plant any remaining bulbs, and start onions and the slowest transplants indoors late in the month.
Zone 8b (lower Coastal Plain & Lowcountry): mild winter gardening continues. Cold frames and row covers carry greens, lettuces, and roots, and on a warm day you can plant English peas, onion sets, and the first potatoes in a sheltered bed.
What's at the Farmers Market
December markets in South Carolina are quieter but anchored by the winter staples and the holiday table. Frost-sweetened collards — essential to a Lowcountry New Year — lead the greens, with kale, mustard and turnip greens, cabbage, broccoli, cauliflower, and spinach, alongside sweet potatoes, winter squash, turnips, rutabagas, beets, and the fresh pecan crop.
Storage apples, onions, and garlic fill in, and the first coastal satsumas and other cold-hardy citrus from the Lowcountry appear at some markets — a Southern winter treat. Local honey, stone-ground grits and cornmeal, Lowcountry preserves, and boiled peanuts hold their place, and the winter and year-round markets in Charleston, Columbia, and Greenville keep local food moving. Choose collards with firm, deep-green leaves and refrigerate loosely wrapped, pick sweet potatoes firm and store them cool and dry but never refrigerated, choose pecans heavy that don't rattle, and select satsumas heavy for their size with glossy skin for the best fruit.
Night Sky This Month
December's long, cold, clear nights bring the year's finest stargazing to South Carolina. The darkest skies are in the Upstate at Caesars Head and Table Rock State Park, over the wide ACE Basin marshes, and along the unlit beaches at Huntington Beach State Park, where regional astronomy clubs hold winter star parties in the crisp, dry, transparent air. The winter solstice near December 21 brings the year's longest nights.
The brilliant winter constellations dominate the evening: Orion strides up the southeast, his belt pointing down to dazzling Sirius, the sky's brightest star, with Taurus and the Pleiades cluster riding high and the great Winter Hexagon wheeling around them. The Geminid meteor shower — one of the best of the entire year — peaks around December 14, sending many bright, slow meteors across the sky, best from a dark site in the evening and after midnight. The Orion Nebula glows in Orion's sword in binoculars. The printable South Carolina night-sky guide lists this year's exact Geminid peak dates, planet positions, and the best dark-sky locations.
Butterflies & Pollinators
December all but ends butterfly flight in South Carolina's Upstate, but the mild Lowcountry can still surprise on the warmest days. On a sunny December afternoon along the coast, a hardy cloudless sulphur, gulf fritillary, common buckeye, or American lady may take wing, and overwintered mourning cloaks, eastern commas, and question marks may stir from their shelters statewide during a warm spell.
Most species are deep in their overwintering stages. The butterflies that pass the winter as adults are tucked behind loose bark, in woodpiles, and in outbuildings; the eastern tiger swallowtail and its relatives wait as chrysalises camouflaged against twigs; the coastal palamedes swallowtail overwinters as a chrysalis in the redbay swamps of the ACE Basin and Francis Marion; and many skippers and whites pass the cold as eggs or larvae in the leaf litter and on their host plants. Monarchs have cleared the state for the Mexican forests. Leaving leaf litter, standing stems, seed-heads, and brush piles undisturbed through winter is the single best thing a South Carolina gardener can do to protect next summer's butterflies.
Trees This Month
December reveals the bare architecture of South Carolina's deciduous forests in the Upstate and Piedmont while the Lowcountry holds its evergreen green. It is the month to read bark and form — the shaggy strips of shagbark hickory, the smooth gray of American beech holding bleached marcescent leaves, the broad blocky bark of mature white oak, and the flaking camouflage trunks of sycamore along the Piedmont rivers.
The evergreens define the South Carolina winter. Along the coast and through the Lowcountry, spreading live oaks draped in Spanish moss, the fan-fronded cabbage palmetto (the state tree), southern magnolia, wax myrtle, and American holly hold the landscape green, while the russet ranks of dormant bald cypress and swamp tupelo, now mostly bare, rise from the blackwater swamps. The Sandhills and Piedmont carry loblolly, shortleaf, and the iconic longleaf pine, holding its long needles and open green crowns above the wiregrass. The American and yaupon hollies glow with red berries for the holidays, and the buds are set and waiting on every twig for the early Southern spring.
