Stems & Roots: Stems slender, soft, smooth, much-branched, at first erect but soon matted or spreading over nearby vegetation; leaves in whorls of 6 to 8 per node, narrowly oblong or wider towards the end, 1-3cm (2/5-1¼in.) long, bright green.

Flowers & Fruit: Flowers in loosely branching clusters at the ends of stems and on short branches throughout the plant; each flower with 4 tiny white petals, 2-4mm (1/12-1/6in.) across, sitting on top of a small spherical ovary which develops into the fruit ("seed"). Flowers from June to August.

Habitat: Smooth bedstraw occurs throughout Ontario in pastures, meadows, river flats, roadsides and occasionally in lawns and gardens. There are several other kinds of perennial white-flowered bedstraws in Ontario but they are rarely considered weedy.

Similar Species: It is distinguished by having usually 6 or 8 leaves per node on the smooth stems and branches.
