Scarlet rātā vine

Metrosideros fulgens · Myrtaceae · all Metrosideros records · also called Climbing rātā · Wikipedia

Fire-resistant. Recommended by the one independent primary-evidence lineage to have rated it so far (A quantitative assessment of shoot flammability for 60 tr…), with no objection on record. Limited evidence: a single lineage — more sources may still move this verdict. This status is computed from the cited evidence by the published rule, never hand-assigned.

▲ A quantitative assessment of shoot flammability for 60 tr… · fire-tested

Computed class: Fire-resistant (limited-evidence) — derived from the cited evidence by a published rule, never hand-assigned. Each chip above is one independent primary-evidence lineage and its direction. No plant is fireproof; condition and placement govern. Zone 0 is hardscape regardless.

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.

Mid-scale / conditional (1)

“Moderate flammability category (Fig. 2)”

Shoot category from the paper's cluster analysis; samples were air-dried for 24 hours before testing.
