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
- Fire-resistant — 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
- 2 source placement records; source schemes remain separate.
- Evidence regions
- Catalonia, Spain; Global; Mediterranean southeast France; Michigan / Great Lakes; Nevada / Great Basin; South Carolina; Utah / Intermountain West; Valencia, Spain / western Mediterranean; Yavapai County, Arizona
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 5 scopes across 5 cited fire sources
- Wildfire-resistant Landscape Plants for Michigan (Extension Bulletin E2948) · Official scoped edition
- Landscaping Can Be Attractive & FIREWISE (Fire Smart Plant List for SC) · Official scoped edition
- A Compilation of Good Plant Choices for Nevada's High Fire Hazard Areas (SP-05-16) · Official scoped edition

2. Why this plant is relevant here
- State distribution
- Documented in MI.
- 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.

Firewise Plants for Utah Landscapes (NR/FF/002)
“listed as a firewise plant for Utah landscapes”
Source says the plant can be firewise when properly used and maintained. Source table name: Pyracantha species.
-
Sensibilité des haies face aux incendies de forêt sous climat méditerranéen
“Faible fire sensitivity”
The fiche's overall sensitivity combines experimental-bench inflammability, intensity, and combustion measurements with foresters' observations of fire damage.

Wildfire-resistant Landscape Plants for Michigan (Extension Bulletin E2948)
“considered wildfire-resistant and are recommended for Michigan’s climate”
Table 1 row: Pyracantha spp. (Pyracantha).
-
Landscaping Can Be Attractive & FIREWISE (Fire Smart Plant List for SC)
“LESS Flammable Plants with some fire resistance”
Listed as Pyracantha, firethorn. The source says highly flammable plants ignite faster and burn readily; less flammable plants have some fire resistance.
Avoids (2)
-
“DESACONSEJADA”
Pyracantha spp. 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.
-
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34)
“Fire-Prone Plants”
Listed as Firethorn — Pyracantha 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.
