Tussilago farfara appears in three legal-list rows, naming ME, MA, and WA. Those jurisdictions remain explicit so the regulatory geography is not flattened into a national claim.
The available pack is limited evidence. Its supporting coverage is shown in the cited entries, without filling the record with conditions or values not present in the selected facts.
One ecological invasive report accompanies the legal listings. It remains an ecological source within this profile, while the evidence table preserves the narrow basis for the limited-evidence classification.

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.
Listed without a rating (48)Corroboration (48 rows from 1 source)
