Goldmoss stonecrop has favorable fire-resistance recommendations from Montana and California plant guides.
Montana State University Extension includes Sedum acre among fire-resistant plants adapted to the state. There is no numerical grade attached to that entry: appearing on the list is the recommendation. The guide provides a regional starting point for selecting this perennial, rather than a measured ignition threshold.
The California evidence works through earlier references. In the Diablo Firesafe Council’s favorable-performance table, goldmoss stonecrop has three supporting references and is described as a creeping succulent. Those references did not share a consistently defined set of rating terms. Their agreement shows a history of favorable advice; a standardized test result would be a different kind of evidence.
For a gardener comparing low-growing plants, the useful finding is that both guides favor this particular stonecrop. The strength of that answer rests on practical plant selection, with limited primary evidence behind the fire-resistant label.

1. Fire evidence and conditions
Fire evidence
Fire-resistant — 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 April 2022 MontGuide explicitly presents fire-resistant species adapted to Montana. FireApproved publishes 92 exact plant records from the source while retaining excluded genus, family, and unresolved rows; the guide itself says not every listed species grows in every part of the state.

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 7,10,53)”
The Diablo Firesafe Council Guide to Plants lists Sedum acre (Goldmoss sedum) as creeper, succulent, 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 (7,10,53). 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.
