Yellow Spring bedstraw is highly flammable in the cited Tlemcen study, making Galium verum a poor choice for fire-resistant planting near structures.
The study of plant communities in western Algeria places this herbaceous species in its high-flammability group. It separately describes its combustibility as moderate and its combustion intensity as strong. Those classifications concern different aspects of burning; the moderate combustibility label does not reverse the high-flammability finding.
The researchers sampled vegetation in spring and used an infrared burner for their experiments. Their conclusions belong to that sampled vegetation and experimental setting. They are not a demonstration that every growing plant will burn identically in a garden.
FLAMITS carries a flame-height observation from the same research. That compilation adds a way to inspect the underlying measurement, rather than another independent assessment. For a planting decision, the published high-flammability classification is the reason to avoid treating this bedstraw as a fire-resistant selection.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and
introduced describe biogeographic relationship, not fire performance or planting approval.
Doubtful and extinct rows stay visible but do not count as current presence.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
3 cited rows from this source; its identity, lineage and tier are stated once.
