Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Highly flammable — location does not change the cited classification.
- Fire-performance conditions
- No test or rating condition is normalized.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 3 source placement records; source schemes remain separate.
- Evidence regions
- Ashland, Oregon; Catalonia, Spain; Mainland Portugal; Yavapai County, Arizona
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 2 scopes across 2 cited fire sources
2. Why this plant is relevant here
- State distribution
- Documented in AZ.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- USDA hardiness
- No hardiness value is normalized.
3. Legal, ecological, and broader status
- Legal-list status
- Set a location for an exact legal-list result; source silence is not clearance.
- Seed-list status
- Set a location to compare the separate state noxious-weed seed layer.
- Reported invasive here
- No ecological invasive report is normalized; that does not prove noninvasiveness.
- Broader regional context
- Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
- Federal context
- Federal designations remain separate from state legal-list results.
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.

Where its sources say to plant it
- Prohibited Flammable Plants: new planting or propagation restricted within 30 ft of any structure
- Selective Shrub Management to Preserve Mediterranean Fore…: selectively control in fuel-management bands in mainland Portugal
- Guía de pirojardinería: suitable inside or outside the 25-metre maximum-risk zone
The evidence
Recommends (1)
-
“MUY RECOMENDADA”
Cytisus spp. is rated “MUY RECOMENDADA” 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.
Avoids (3)
-
Prohibited Flammable Plants (Ashland Municipal Code 9.04)
“prohibited flammable plant”
The City of Ashland restricts new planting or propagation within 30 ft of any structure, including structures on adjacent lots (AMC 9.04).
-
Selective Shrub Management to Preserve Mediterranean Forests and Reduce the Risk of Fire
“Control”
Table 2 places this genus in the Control column. The authors describe the control group as heliophilous vegetation associated with fine fuels and traits linked to faster combustibility or greater flammability; this is a selective fuel-band management decision, not a global prohibition.
-
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34)
“Fire-Prone Plants”
Listed as Broom — Cytisus sp.. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
