Fan palms is a limited-evidence record. The classification reflects the source coverage preserved in the evidence table, without filling gaps in that pack with a broader claim.
The selected fire condition is green. Its citation context is presented under performance conditions, keeping the material state explicit wherever the sourced result is read.
This is a genus-rank umbrella record, so the page gathers evidence for Washingtonia rather than presenting a species account. The entries supporting that genus-level scope remain in the source table, beside the limited-evidence classification they produce.

1. Fire evidence and conditions
Fire evidence
Fire-resistant — location does not change the cited classification.
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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
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.
Landscape for Fire Protection: irrigated hillsides [maire-1968-fire-protection-landscape] (with its recommendation)
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.
Washingtonia (Fan palms) appears in the source's conditioned examples for landscaping irrigated hillsides. Fuel volume is to be minimized, plants watered to their needs, and accumulated litter removed.
