Valette's 1990 shoot study supplies the fire evidence for Cytisus triflorus, whose accepted name is Cytisus villosus. At INRA Avignon, the shoot series had note 2 as its high point during July, August, and September on the study's 0–5 scale, and the original description was “modérément inflammable.”
One recommendation underlies the record, so its status remains limited evidence. Separately, the ecological channel records one introduced-established report for the Lower 48. That report describes establishment status; it does not contribute to the fire verdict in the evidence table.
The citation and monthly notes are available in the source table. Comparisons and the genus index provide broader navigation without treating neighboring records as extra support for this species.

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.
