Biology

Catchweed bedstraw is a weakly erect to sprawling plant from a slender taproot. Stems are weak, climbing or twining to over six feet in length. The stems are square in cross-section with short, downward-pointing bristles along the ridges. Narrow leaves occur in whorls of six to eight, with backward-pointing bristles along the leaf margins. Small, four-petalled, white flowers are produced on short stems in the leaf axils. Fruits consist of two nearly round structures joined along the center. The seeds are covered with hooked hairs which aid in dispersal. This plant spreads only by seeds, but a related species (northern bedstraw, Galium boreale) is a perennial with a spreading root system. SPECIAL INFORMATION: The clinging seeds and stems of catchweed bedstraw can be a nuisance on animals or in clothing.

Habitat

Catchweed bedstraw is often found in uncultivated areas such as along fencerows, under trees, or in brushy areas. From there, the plant can spread into gardens, fields, ornamental plantings, and other cultivated sites.
