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.
Celtis laevigata · Cannabaceae
The Piedmont's warty-barked floodplain hackberry — sweet orange drupes that all but grow themselves.
Community photos of Celtis laevigata — fix this search image in your eye before the hike (leaf, flower/bract, ripe fruit, bark, whole-plant habit).
Sugarberry is the common, widespread large hackberry of the NC Piedmont bottomlands; common hackberry (C. occidentalis) is scattered/uncommon here and more frequent in the mountains and upper Piedmont uplands; dwarf hackberry (C. tenuifolia / pumila) is rare on basic rock outcrops
Best bet: Hand-strip ripe drupes, soak overnight and rub the thin pulp off the pits on a screen (float away pulp and empty seeds). Cold-MOIST stratify cleaned pits in damp sand/perlite at ~40°F (5°C) for 60–90 days (up to 120 d boosts germination), then sow ~1/2 in. deep in spring; germination is good and seedlings robust. Fall-sowing cleaned pits in a protected outdoor bed lets winter do the stratifying. No scarification or acid treatment needed.
A tough Piedmont native — thrives in heavy clay, tolerates periodic flooding, drought once established, compaction and heat (zone 7b/8a). Not invasive, but fast and self-sows freely, so expect volunteers; brittle wood makes it a poor choice near targets. Cosmetic hackberry nipple-gall and (mainly on C. occidentalis) witches'-broom don't threaten tree health.
Hackberries read as "elm that isn't an elm." Build your search image around bottomlands: sugarberry (Celtis laevigata) is the common large hackberry of the NC Piedmont, hugging stream banks, river floodplains, and moist alluvial flats, plus mesic fencerows and disturbed edges on heavy soil. The fastest lock-on is the bark — pale gray, mostly smooth, but studded with distinctive corky warts and short ridges unlike anything else in the woods. In September–November the crown carries small orange-red to purplish-brown drupes and turns a soft pale yellow, both easy to spot against a still-green understory.
Collect Sep–Nov, taking only fully colored drupes — orange-red deepening to purplish-brown. Skip green summer fruit: it's immature and germinates poorly, so a July pass is wasted effort. Soak the drupes overnight and rub the thin pulp off the pits on a screen, floating away pulp and empty seeds. The pits have innate dormancy: cold-moist stratify in damp sand/perlite at ~40°F for 60–90 days (up to 120 d gives very high germination), then sow about a half-inch deep in spring — germination is good and seedlings vigorous. Alternatively fall-sow cleaned pits in a protected outdoor bed and let winter do the work. No scarification or acid treatment needed.
Around Roxboro/Person County, work the floodplains and shorelines of Mayo Lake Park and Hyco Lake and the Hyco/Dan River bottoms. Farther south, the Eno River State Park floodplain (Durham/Orange) is reliable hackberry ground, and nearby Occoneechee Mountain State Natural Area — with its mafic/basic slopes — is the best local bet for the rarer dwarf hackberry. Falls Lake bottomland edges round out the list. Focus on moist, disturbed alluvial ground; that's where sugarberry concentrates.
