A field-to-nursery notebook: foraging native seeds & cuttings across North Carolina, identifying them, and working out how to grow them for a NC Piedmont native-plant nursery.
Ulmus alata · Ulmaceae
The Piedmont's corky-winged upland elm — grab the reddish spring samaras and sow them fresh, not in fall.
Community photos of Ulmus alata — fix this search image in your eye before the hike (leaf, flower/bract, ripe fruit, bark, whole-plant habit).
Common throughout the NC Piedmont and into the Coastal Plain; a characteristic dry-upland tree in Person County and central NC. Verified via NC Extension and BONAP/USDA county records.
Best bet: SOW FRESH, immediately. Elm samaras are essentially non-dormant and lose viability within weeks of drying, so the highest-odds route is direct spring sowing: scatter whole or lightly de-winged seed on a moist flat/bed, barely cover (~⅛ in), keep evenly damp at 70–85°F — expect germination in about 2–4 weeks, same season. If you must hold seed, air-dry briefly, refrigerate dry, then give 30–60 days cold-moist stratification at 36–40°F before sowing — but fresh spring sowing beats stored seed every time.
A true Piedmont upland native — genuinely happy on heavy clay, hot humid summers and drought-prone poor ground where most nursery stock struggles (zones 6a–9b, so 7b/8a is well within range). More Dutch-elm-disease resistant than American elm, though not immune (also watch elm leaf beetle), so avoid monoculture blocks. Two honest cautions: it sets prolific seed and root-sprouts, so it volunteers readily into old fields, beds and fencerows; and the corky-winged twigs make it only a modest ornamental — best used as a tough, fast, wildlife-value shade/hedgerow tree.
Winged elm is the elm you'll actually trip over in the Piedmont uplands — not the storybook American elm of river bottoms, but a tough medium tree of dry ridges, fencerows, old fields, roadsides and powerline cuts on the heavy red clay around Roxboro. Build your search image around two things: the crown and the twig. From a distance in February–March it flushes a haze of tiny reddish flowers on bare branches; by March–April that becomes a fog of pale reddish-tan samaras — your collection cue. Up close, the giveaway is the twig: broad, thin corky wings running in opposite pairs down the branchlets. No other native Piedmont elm wears them so boldly.
This is the spring-samara gotcha: winged-elm seed ripens in March–April (into early May), not fall. If you show up in autumn you'll find nothing to collect. Time it to when clusters dry from red to tan and wings shed at a touch — strip whole clusters or catch a fresh drop on a tarp, and check that central seeds are plump, not flat/aborted (a big fraction of every elm crop is empty).
Then sow fresh, immediately. Elm samaras are essentially non-dormant and lose viability within weeks of drying, so direct spring sowing is far and away the highest-odds route: scatter whole or lightly de-winged seed on a moist flat, barely cover, keep damp at 70–85°F — germination in about 2–4 weeks, the same season. Only if you must store should you air-dry, refrigerate dry, and give 30–60 days cold-moist stratification (36–40°F) before sowing. Seedlings size up fast for a first-year liner.
Work the dry upland edges around Roxboro first: Mayo Lake Park and Hyco Lake shorelines, Person County game lands, and any old-field fencerow or powerline right-of-way. Farther south, Eno River State Park, Occoneechee Mountain (Hillsborough), and Duke Forest all hold reliable winged elm. Scout in Feb–Mar bloom to mark trees, then return in Mar–Apr with a tarp for ripe seed.
