Northern bedstraw

Galium boreale

Northern bedstraw (Galium boreale) fills the northern prairie with frothy white flower clusters in June and July. Its shallow rhizomes weave through the stand, and its small open flowers are accessible to tiny native bees and flies that larger blossoms exclude.

Why landowners plant northern bedstraw

  • Feeds small-bodied native bees, flies, and beetles that specialize on open flowers.
  • Covers the early-summer bloom period in northern CP42 mixes.
  • Rhizomatous growth knits the soil surface without becoming dominant.
  • Tolerates partial shade at savanna and shelterbelt edges.

Site fit

Mesic to dry-mesic loam and sandy loam in the northern tier states. Not adapted to hot dry southern Plains sites or to standing water.

Establishment

Cold-moist stratification required — dormant-seed. Plant shallow. Establishment is moderate; first bloom typically in year two or three.

Management

Fire-tolerant with a spring burn rotation. Does not need mowing once established. Avoid broadleaf herbicide.

Frequently asked questions

Is northern bedstraw invasive?

No. It spreads modestly by shallow rhizome but stays a minor component of a diverse stand.

Which pollinators use northern bedstraw?

Small native bees, syrphid flies, and beetles — insects that need shallow, open flowers rather than deep nectar tubes.
