Facts
Boreal bedstraw is a native bedstraw with a disjunct distribution that includes northeastern and northwestern North America. It is very rare in New England, with a few populations each from Maine, New Hampshire and Vermont in boreal and subalpine forests, seeps and stream banks, often associated with bryophytes.
Habitat
Forests, shores of rivers or lakes
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

9. Galium kamtschaticum Steller ex J.A. & J.H. Schultes NC
boreal bedstraw. ME, NH, VT. Boreal and subalpine forests, seeps and stream banks in northern and/or mountainous areas, often associated with abundant bryophyte cover.
Native to North America?
Yes
Sometimes confused with
- Galium boreale:
- corolla cream-white, schizocarp glabrous or with hairs that are not hooked at the apex, and leaf blades 1-2.5 mm wide (vs. G. kamtschaticum, with the corolla yellow-white, schizocarp with uncinate bristles, and leaf blades mostly 5-25 mm wide).
- Galium circaezans:
- flowers with green-purple petals, some of them borne sessile along the branches, and leaf blades 20-50 mm long(vs. G. kamtschaticum, flowers with yellow-white petals, all of them borne on pedicels, and leaf blades 10-30 mm long).
