Canna has an on-list result recorded on the evidence table. Its limited evidence label remains beside the result, showing that direction and depth of support are separate facts. The page does not turn that pairing into a broader source claim.
This entry is a genus-rank umbrella record, preserving the level at which the source named Canna. The related plants section allows comparison without assigning this result to another species. A return to the source rows keeps the on-list direction, limited support, and umbrella scope connected to the record that actually carries them.

Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.

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.
