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
- Mixed evidence — location does not change the cited classification.
- Fire-performance conditions
- 1 condition stated in cited fire-evidence rows.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 4 source placement records; source schemes remain separate.
- Evidence regions
- Dorset, United Kingdom; Florida; Kentucky; Louisiana; Nevada / Great Basin; Oregon (Willamette Valley); South Carolina; Yavapai County, Arizona
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

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.

The source's common-name box lists viburnum. This record preserves only the exact genus-level identity supported by that label.
-
Fire-resistant Landscape Plants for the Willamette Valley (EM 9103)
“fire-resistant plants that thrive in Willamette Valley growing conditions”
The shrubs & woody vines profile lists Viburnum spp. as Viburnum and Blackhaw. The profile prints USDA Hardiness Zone: Varies by species.
-
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34)
“Fire-Resistant Plants”
Listed as Viburnum — Viburnum 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.
