Brugmansia has an avoid recommendation in the evidence table. That conclusion leads the x candida hybrid profile and remains attached to this named record rather than extending to every brugmansia.
The accepted fire-source pack is limited evidence. Its cited entries show the available support without adding a performance claim or condition beyond the sources selected for the record.
Same-form alternatives appear under related plants. They provide a direct comparison path for the avoid recommendation while retaining their own records and evidence. The alternative list therefore stays useful without being treated as additional support for this hybrid.
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.
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.
Brugmansia x candida is rated “DESACONSEJADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
