Is this one for your yard?

Enter your ZIP to see whether this is legal to plant in your state, and whether it survives your winter.

Black Wattle opens with the fire-resistant plant source. The evidence table records limited evidence for that selected lab lineage. The compact label keeps the source title attached to one row.

The 1 seed-list row remains in the seed-list, while 2 ecological invasive reports are recorded outside the fire tally. These facts answer separate regulatory, ecological, and fire-evidence questions for Acacia mearnsii. Keeping the domains apart prevents either local status from becoming an additional lab position. A return to the source rows keeps the limited lineage visible beside those separate domains.

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.

Where its sources say to plant it

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.

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.
