A fire-resistant plant-list citation is the source selected for hickory wattle. It records Acacia penninervis on-list in the evidence table, while the page keeps the limited-evidence marker visible. No unselected test condition or performance value is introduced to make that listing sound more precise than it is. A second fire source is not selected.

The underlying entry remains available without fragmenting its title. The related-plants section answers the comparison question separately, and the genus page gives a wider genus view while leaving this hickory wattle result bound to its cited row.

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.
