The leaf-ranking row places Lingonberry among the ten taxa with the worst fire resistance after analysis of six litter-leaf traits. Its cured state remains explicit in performance conditions.
The measurement rows record a flaming temperature of 258 degrees Celsius and calorific values of 4,994.5, 5,120, and 5,160 kilocalories per kilogram across live leaves and dead stems. They are not further verdicts, so the record stays limited evidence.
The ranking supports the avoid result shown in the evidence table. related plants retain the existing route to same-form alternatives without transferring this species' measurements to them.
Highly flammable — location does not change the cited classification.

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.
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.
