The flame-wave row describes Twin-flower Knawel as fire-retardant: it resists the first flame wave but may burn once dried. That is the source wording for Scleranthus biflorus.

The record uses this single directional row for its on-list result. Its distinction between initial resistance and later burning remains visible in the evidence table, without being shortened to a broader performance claim.

With no second fire source present, the page remains limited evidence. Its context is Victoria; the cited row retains the full statement, and related plants continues the comparison path.

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.
