DistributionMostly Piedmont, but also southern and central Mountains and northern Coastal Plain.

MA to PA, IN, and NE, south to GA, LA, and central TX.
AbundanceFairly common in the Piedmont; infrequent in the southern and central Mountains and in the northern Coastal Plain. Not nearly as numerous as L. acuminata and L. echinata in the Piedmont.
HabitatMesic to moist or dry soils of roadsides, fields, woodland and forest borders, open mixed woodlands. Generally not in rich or moist soil.
PhenologyFlowering and fruiting late March-July.
IdentificationBulbous Woodrush rarely exceeds a foot tall. Like L. echinata and L. multiflora, most leaves are basal and near-basal and wispy-hairy, and the inflorescence has rather short branches. Each head contains 6-20 flowers and is longer than wide. Bulbous Woodrush and Common Woodrush (L. multiflora) have strongly ascending or erect branches, versus often spreading on longer branches in Hedgehog Woodrush (L. echinata). The characteristic, whitish bulblets occur on some roots, but are not always present.
Taxonomic CommentsSome older references had this taxon as part of L. campestris, which now has been split out into this species, L. echinata, and L. multiflora, if not others.
