Golden spaniard, Aciphylla aurea, is an avoid entry in the evidence table. Its one rated source gives the perennial's shoots a very-high-flammability classification.

For predried shoots, measurements record complete ignition, a maximum near 737°C, burning lasting about 231 seconds, and roughly 56% estimated consumed biomass. These non-rated values describe tested behavior without casting more recommendation votes. The conclusion therefore remains limited evidence.

Revisit the source table to separate that classification from the measurements. Same-form alternatives support comparison, while the genus index retains each Aciphylla record with its own source set.

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.

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.
