California redbud is rated fire resistant, and every cited assessment recommends it.
The clearest test-based support comes from the University of Exeter wildFIRE Lab and its Dorset partners. They placed Western redbud in their green traffic-light class, meaning low risk even during drought. Utah State University Extension also calls it firewise when properly used and maintained, while the University of Nevada Cooperative Extension includes it among plants supported by at least two western sources.
California compilations point the same way. The University of California Forest Products Laboratory found California redbud recommended by thirteen references for high-fire-risk areas. The Diablo Firesafe Council likewise places it among plants receiving favorable ratings from at least three references. Those compilations deserve some caution because their publishers say many underlying lists used undefined ranking terms, and the university report says those lists often lacked a scientific basis. Still, their agreement is reinforced by the separate laboratory rating.
California redbud, also called Western redbud, is a tree in the Fabaceae family and is native to the southwestern and northwestern United States. The practical conclusion is favorable: it is a defensible fire-resistant choice, especially when its placement and maintenance follow the conditions attached to the Utah recommendation.

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 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.
University of Nevada Cooperative Extension compiled plants suited to Nevada climate zones and reported favorably by at least two upstream firewise lists. FireApproved publishes 126 exact source owners at Nevada publication scope. The source explicitly makes no independent flammability determination, so these rows remain corroborative.
Utah State University Extension states that this fact sheet selects examples for Utah landscapes and that they require proper placement and maintenance. FireApproved publishes 83 exact source owners at Utah publication scope. The table is not a site-specific planting clearance.

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 8,9,11,12,15,17,25,30,34,40,41,42,53)”
The Diablo Firesafe Council Guide to Plants lists Cercis occidentalis (Western redbud) as tree, evergreen, in Table 1: plants with a favorable fire performance rating in 3 or more references. The guide cites 13 of its 57 numbered references for this row (8,9,11,12,15,17,25,30,34,40,41,42,53). 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.
