Golden-yarrow has repeated favorable fire-performance ratings, but those listings do not establish that the shrub is fire resistant.
The University of California Forest Products Laboratory reports that three underlying references recommended golden-yarrow for use in high-fire-risk areas. The Diablo Firesafe Council traces golden-yarrow's favorable rating to references 40, 41 and 53. These are compilations of earlier recommendations, so their agreement shows repetition rather than an independent primary finding.
Both compilations use recommendations whose ranking terms were often undefined. The university laboratory also warns that the underlying plant lists often lack a scientific basis.
Golden-yarrow is an Asteraceae shrub native to the southwestern United States. Its repeated favorable treatment makes it reasonable to consider for a high-fire-risk area, but the available sources do not take a clear primary position on fire resistance. Calling golden-yarrow fire resistant would claim more than these compiled recommendations establish.

Mixed evidence — location does not change the cited classification.
The guide presents itself as fire performance ratings for common landscape plants in a fire-prone California setting. FireApproved publishes 104 exact owners as republished California context. It is not an independent rating, a current endorsement, or parcel suitability.
The UC Forest Products Laboratory says the guide covers properties of common California landscaping plants and was prepared for California fire agencies. FireApproved publishes 130 exact owners at historical California publication scope. The report is a 1997 compilation, not a current endorsement, site rating, or independent test of every row.

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.

“Table 1: favorable fire performance rating in 3 or more references (refs 40,41,53)”
The Diablo Firesafe Council Guide to Plants lists Eriophyllum confertiflorum (Golden yarrow) as shrub, perennial, in Table 1: plants with a favorable fire performance rating in 3 or more references. The guide cites 3 of its 57 numbered references for this row (40,41,53). The guide states the ranking terms in its underlying references were mostly undefined and makes no attempt to rank within the list, and that fire performance is compromised without maintenance.
