The accepted rows compute to avoid and keep 1 ecological invasive report as separate context. Same-form alternatives are cited under related plants, where comparison does not add source rows to this azalea. The resulting boundary is species-specific: the leaf-ranking study supplies the laboratory anchor, cured identifies its condition, and neither the ecological report nor the alternatives expands the limited fire pack for R. simsii.
Highly flammable — location does not change the cited 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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
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.
14 cited rows from this source; its identity, lineage and tier are stated once.
