Arkansas Nature Guide: May 2026
May is full, lush late spring in Arkansas — the breeding birds are in full song across the Ozark and Ouachita forests, the last spring migrants pass through, and the gardens and markets fill with the first real abundance of the year. The Natural State is at its greenest and most alive.
What to look for this week
- Vast flights of mallards, pintail, and snow geese pack the flooded rice fields and refuges around Stuttgart at the height of the Delta duck season.
- The Quadrantid meteor shower peaks around January 3 in a short, sharp burst; look toward the northeast after midnight from a dark Ozark sky.
- The bare bottomland sycamores glow with their white, peeling upper bark against the gray winter woods of the Cache River.
- A planning and pruning month statewide; order seeds early and prune dormant fruit trees and muscadines on mild days.
Birds This Month
May is one of Arkansas's premier birding months, as the tail of spring migration overlaps with the full breeding season. Early in the month the last warbler waves move through — blackpoll, magnolia, Tennessee, and Canada warblers pass through on their way north — while the breeding warblers settle on territory: the golden prothonotary in the Cache River swamps, the worm-eating and hooded warblers on the Ozark and Ouachita slopes, and the secretive swainson's warbler in the Big Woods cane.
The forest is at its fullest song. Wood thrushes, scarlet and summer tanagers, indigo buntings, and yellow-billed cuckoos fill the canopy, and the painted bunting — one of North America's most spectacular birds — sings from brushy edges in the south and the Arkansas Valley. The elegant scissor-tailed flycatcher is now nesting across the Valley and west, performing its tumbling courtship flight over the prairies.
Ruby-throated hummingbirds are nesting, Eastern bluebirds and Carolina wrens are on second broods, and the state bird, the Northern mockingbird, sings through the night. At the western edge, Greater Roadrunners and painted buntings add a southwestern flavor to the Arkansas list.
This month's tip: the breeding-bird dawn chorus peaks now — go out early to an Ozark or Ouachita forest trail to hear wood thrushes, tanagers, and warblers at their fullest, and visit the Arkansas Valley or south Arkansas for the dazzling painted bunting, a bird many travel across the country to see.
What's Blooming
May moves Arkansas's wildflower show from the shaded woods out into the sun. As the forest canopy closes and ends the woodland ephemerals, the open glades, prairies, and roadsides take over. The native wild azalea finishes on the higher mountain slopes, and the glades of the Arkansas Valley and Ouachitas glow with blue wild indigo, Indian paintbrush, prairie phlox, and coreopsis.
The roadsides and meadows fill with color. Ox-eye daisy, black-eyed Susan, spiderwort, and Indian pink bloom along the woodland edges, and on the remnant Grand Prairie near Stuttgart the early prairie flowers — pale purple coneflower, prairie clover, and compass plant leaves — rise above the greening grass. In wet places, the brilliant fire pink and the first milkweeds open for the returning monarchs.
Where to see it: the dolomite and sandstone glades of the Arkansas Valley and Ouachitas, the prairie remnants of the Grand Prairie, and the mountain roadsides of Petit Jean, Mount Magazine, and the Talimena Scenic Drive are at their best now. Look for the wild indigo and paintbrush on open slopes, and walk the prairie remnants to catch the start of the long summer prairie bloom that runs through the warm months ahead.
Garden This Month
May is the lush, productive heart of the Arkansas growing season, and with frost behind every part of the state, the warm-season garden is in full swing. Finish setting out tomato, pepper, and eggplant transplants and sweet potato slips early in the month, and keep direct-sowing the heat-lovers as the soil warms — okra, southern (field) peas, squash, cucumbers, melons, and successive plantings of bush beans and sweet corn. Okra and southern peas in particular thrive in the building Arkansas heat and are classic Southern garden staples here.
The cool-season crops are finishing — harvest the last lettuce, spinach, peas, and broccoli before they bolt in the warmth, and pull spring radishes and turnips. As the heat builds, begin mulching beds to hold moisture and suppress weeds, and set up consistent watering for the tomatoes and peppers. Stake and cage the tomatoes now while they are manageable, and watch for the first squash bugs, cucumber beetles, and tomato hornworms. May rains are usually generous, but be ready to water deeply if a dry spell sets in toward month's end.
Zone 6b (upper Ozarks, Fayetteville and the northwest): with the last frost finally past, the warm-season garden goes in fully. Set out tomatoes, peppers, eggplant, and sweet potato slips, and direct-sow beans, squash, cucumbers, corn, okra, and southern peas as the soil warms. The upper Ozarks gives you a slightly cooler, longer window for tomatoes.
Zone 7a (Ozark and Ouachita valleys, Little Rock area): the warm-season garden is in full swing. Finish setting tomatoes, peppers, and sweet potato slips early in the month, keep direct-sowing okra, southern peas, squash, and successive beans, and begin mulching and watering as the heat builds. Watch for early pests on the squash and tomatoes.
What's at the Farmers Market
May is when Arkansas markets hit their first real stride of abundance. The signature crop now is the strawberry, in full season across the state — choose fully red, glossy berries with fresh green caps, since strawberries do not ripen further once picked. Alongside them come the last of the spring crops at their peak: asparagus, spinach, leaf lettuces, spring onions, spring carrots, and the first new potatoes.
The early summer vegetables begin to appear toward month's end — the first summer squash and zucchini, cucumbers, snap beans, and beets, along with bunches of fresh herbs. This is also the season for the first blackberries from early varieties in the warm south, a preview of Arkansas's famous thornless-blackberry harvest to come. Markets still sell vegetable seedlings for late plantings, plus local honey, pasture eggs, and milled Delta rice.
For selection and storage: refrigerate strawberries unwashed in a single layer and use within a few days, washing only just before eating. Keep new potatoes cool and dark and use them quickly, since their thin skins do not store like cured potatoes. Stand asparagus upright in water in the refrigerator, store greens and herbs dry in the crisper, and refrigerate the first berries unwashed in a single layer to keep them from crushing.
Night Sky This Month
May nights are mild and inviting in Arkansas, perfect for evening stargazing before the deep humidity of summer takes hold. The dark Buffalo National River International Dark Sky Park, the high overlook at Mount Magazine State Park, and the Ouachita National Forest remain the state's finest dark-sky spots, and Arkansas state parks run spring and early-summer star parties through the month.
The spring constellations dominate the early evening. Leo the Lion stands high in the west, Virgo with bright Spica rides the south, and orange Arcturus in Boötes blazes nearly overhead — find it by following the arc of the Big Dipper's handle. The semicircle of Corona Borealis and the sprawling, dim figure of Hercules climb in the east, and within Hercules lies the magnificent globular cluster M13, a glorious binocular and telescope target from a dark Ozark sky.
By late evening, the first of the summer Milky Way begins to rise in the southeast, hinting at the rich star fields of the coming season. The Eta Aquariid meteor shower, debris from Halley's Comet, peaks in early May but favors the pre-dawn hours and is best seen low in the southeast. Because the planets shift position each year, check the printable Arkansas night-sky guide for this year's specific planet visibility and the best clear, moonless viewing nights from your latitude.
Butterflies & Pollinators
May is a rich, busy butterfly month across Arkansas, with the spring species at their peak and summer broods beginning. The monarchs are breeding on milkweed statewide, and the big swallowtails are everywhere — the eastern tiger swallowtail and the iridescent pipevine swallowtail sail through gardens and woodland edges, the spicebush swallowtail works the bottomlands, and the striped zebra swallowtail flies wherever native pawpaw grows.
The fields and edges fill with color. Great spangled fritillaries emerge to nectar on milkweed and coneflower, pearl crescents, red admirals, question marks, and American ladies are common, and the red-spotted purple and hackberry emperor patrol the woodland trails. In the south and the Arkansas Valley, the first Gulf fritillaries push north to breed on native passionflower, adding a flash of tropical orange.
To support them now: a long succession of nectar matters most this month — native milkweed, coneflower, coreopsis, and garden flowers feed the building broods. Keep host plants thriving: milkweed for monarchs, pawpaw for zebra swallowtails, pipevine for pipevine swallowtails, spicebush and sassafras for spicebush swallowtails, and native passionflower for the Gulf fritillaries arriving from the south.
Trees This Month
May is the month the Arkansas forest reaches full, deep summer green. The great spring bloom is over, but a second wave of tree flowers carries on. The tulip tree (yellow-poplar) opens its big orange-and-green tulip-shaped flowers high in the canopy of the rich Ozark and Ouachita coves, and the southern magnolia begins to unfurl its huge, lemon-scented white blossoms in the south and in town plantings.
The bottomlands and edges add their own bloom. The native fringe tree drips its lacy white flowers, the black locust hangs fragrant white pea-flower clusters along roadsides and old fields, and the catalpa opens its showy white, frilled flowers in the lowlands. The sweetgum, oaks, and hickories are fully leafed and setting fruit, the loblolly and shortleaf pines have finished their candles of new growth, and the bald cypress stands lush and feathery green over the Cache River and Delta swamps. The forest is now a closed, shady canopy for the long Arkansas summer ahead.
