Creeper is rated fire resistant, with three expert guides recommending Parthenocissus for fire-conscious gardens.
Valencia’s regional government classifies it as a recommended low-flammability climber. Girona’s provincial government and Catalonia’s fire service also rate Parthenocissus species “recommended” under a garden-suitability method that considers fire research, fuel structure, maintenance, origin, invasiveness, and firefighters’ experience. The University of Arizona Cooperative Extension lists Boston ivy and Virginia creeper as fire-resistant plants, explaining that such plants tend to resist ignition when irrigated and maintained.
The agreement is reassuring, but “fire resistant” does not mean fireproof. The Arizona guidance makes water and upkeep part of its finding, while the Girona method weighs several practical qualities rather than flammability alone. Creeper is therefore a reasonable vine for a fire-conscious planting plan, provided it receives the irrigation and maintenance assumed by the guidance.

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.
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.
Parthenocissus spp. is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
Listed as Boston Ivy, Virginia creeper — Parthenocissus sp.. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
