Thread-leaf bedstraw is a narrow-leaved subspecies of blunt-leaf bedstraw native to moist, shaded habitats along the Atlantic coastal plain. It performs best in consistently moist, organic-rich soil under partial to full shade, making it a charming addition to woodland or rain garden plantings. This low-maintenance native is rarely available commercially but is a rewarding find for native plant enthusiasts.
