Espirea carries an avoid direction in the cited row. The guide says the named hybrid is unsuitable within the 25-metre maximum-risk zone and labels it DESACONSEJADA.
This 2020 qualitative method considers fire evidence together with fuel structure, care, origin, invasiveness, and fire-service experience. It assumes the species receives species-specific maintenance. The evidence table retains that method context. The accepted-name field remains separate from the hybrid spelling.
With no second directional source present, the page remains limited evidence. related plants provides the existing shrub alternatives without extending the guide's zone judgment.
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.

Guía de pirojardinería: not suitable inside the 25-metre maximum-risk zone [girona-2020-iuf-25m-suitability] (with its avoid rating)
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.
Spiraea x arguta 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.
