About Galium lanceolatum (Torr. & A.Gray) Torr.
Galium lanceolatum (Torr. & A.Gray) Torr. is a herbaceous perennial plant. It produces lanceolate leaves with prominent veins, arranged in whorls of four. Its sessile flowers grow in branching terminal clusters; when first open, the flowers are cream-colored, but they quickly turn purple as they mature. The fruits of this species are bristly, bi-lobed capsules. This species is native to the eastern United States and southeastern Canada, found primarily in the Great Lakes region and the Appalachian Mountains. In Canada, it only occurs in southern Quebec and Ontario. In the United States, it ranges from New England in the north southward along the Appalachians, reaching as far south as northern Georgia, northeastern Alabama, and northwestern South Carolina, where it is primarily found in the Ridge and Valley ecoregion and the Blue Ridge ecoregion. Galium lanceolatum is almost exclusively a forest species, occurring most often in mesic forests and wooded slopes. In the Appalachian part of its range, it is frequently found in rich cove forests. This plant typically flowers in June and July, though populations in the southern part of its range may begin flowering as early as late May.
