South Wales wattle has a measured ignition time, but that alone does not establish that it is fire resistant.
This tree, Acacia parramattensis, belongs to the pea family, Fabaceae. Dryad and Global Ecology and Biogeography’s FLAMITS database reports a time to flaming of 33 seconds for leaves classified as live fuel tested in a calorimeter.
Time to flaming measures the delay before a sample produces flames under the test conditions. It does not measure how much heat the leaves release once burning or whether a whole tree survives a fire. The preparation matters: leaves collected as live fuel and then predried are not the same test material as leaves retaining their moisture. The result therefore needs to travel with its experimental conditions, rather than become a general claim about the tree.
The measurement comes from a 2015 University of Sydney doctoral study. FLAMITS preserves the experimental context and does not apply a single resistance threshold across unlike measurements and methods. That makes the figure useful for understanding what was tested, but it supplies no resistant or flammable rating by itself. For someone choosing a garden tree, South Wales wattle’s measured ignition delay leaves its suitability for fire resistance unresolved.

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.
Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and
introduced describe biogeographic relationship, not fire performance or planting approval.
Doubtful and extinct rows stay visible but do not count as current presence.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
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.
