The Idaho Firewise workbook also reports a value of 30, attributed to the Idaho Database. Idaho Firewise draws on field trials in southern Idaho and the Intermountain region, but its described resistance scale runs from 0 to 10. The reported 30 therefore should not be recast as a resistance score or used to invent a planting distance. King County supplies the clearest interpretable finding, while the overall verdict remains fire resistant.
Orange honeysuckle, or Lonicera ciliosa, is a shrub in the Caprifoliaceae family. It is native to the southwestern and northwestern United States, so King County’s western Washington guidance covers part of its native region. For a homeowner choosing among shrubs, orange honeysuckle belongs on the fire-resistant side of the evidence, though the Idaho figure does not provide a usable basis for finer claims about its score or placement.

The official database labels itself "For Southern Idaho" and describes Idaho residents at the urban-rangeland interface. FireApproved publishes 419 existing plant owners that cite its scored rows. This bounded Southern Idaho scope is regional context, not statewide coverage or a conclusion that the score transfers unchanged to every Idaho site.
King County's current wildfire page links this list for the Puget Sound Basin. FireApproved publishes 82 exact source owners as basin context, not statewide Washington guidance or a site-specific recommendation.

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.
Where its sources say to plant it
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.
