1. Fire evidence and conditions

Fire evidence
Fire-resistant — location does not change the cited classification.
Fire-performance conditions
2 conditions 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
Catalonia, Spain; Louisiana; Marin County, California; OR/WA/ID; Oregon; Oregon (Willamette Valley); Pacific Northwest (Oregon / Washington / Idaho); 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
  • Fire-Resistant Plants Common to Marin County · Official scoped edition
    • Marin County (CA footprint); partial normalized coverage · 2019-01-01

      The publication is explicitly limited to plants common to Marin County. FireApproved publishes 104 exact owners as Marin regional context while retaining its placement, spacing, irrigation, and maintenance boundary. It is not statewide California guidance or parcel suitability.

  • Firewise Landscaping (Hammond Research Station) · Official scoped edition
    • LA; partial normalized coverage · 2008-12-02

      LSU AgCenter calls these 31 ornamentals commonly used in Louisiana and recommended for Louisiana firewise landscaping efforts. FireApproved publishes 31 exact source owners, mostly at the source's genus grain. Undocumented curation remains corroborative and is not site suitability.

  • Fire-resistant Landscape Plants for the Willamette Valley (EM 9103) · Official scoped edition
    • Willamette Valley (OR footprint); partial normalized coverage · 2015-02-01

      OSU Extension says EM 9103 highlights fire-resistant plants that thrive under Willamette Valley growing conditions. FireApproved publishes 172 exact owners only as valley context. The guide shares the PNW 590 lineage and is not a second independent vote or statewide site clearance.

  • Fire-Resistant Plants for Home Landscapes (PNW 590) · Official scoped edition
    • ID, OR, WA; partial normalized coverage · 2023-10-01

      The October 2023 joint Pacific Northwest Extension publication explicitly names Oregon, Washington, and Idaho and publishes more than 150 plant profiles. FireApproved has normalized 155 exact plant records from the source; publication scope does not assert that every listed plant suits every site within the three states.

  • Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34) · Official scoped edition
    • Yavapai County (AZ footprint); partial normalized coverage · 2025-03-14

      University of Arizona Cooperative Extension authors Bulletin 34 for Yavapai County. FireApproved publishes 198 exact source owners from its resistant and prone tables and keeps the county boundary visible. County publication scope is regional Arizona context, never statewide scope.

2. Why this plant is relevant here

State distribution
Documented in ID, OR, WA.
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
Documented range 4–10.

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.

Plant hardiness evidence

These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value is not treated as a tolerance range. Different source boundaries stay separate: overlapping statements are compared independently, while only ranges with no shared zone are called a conflict.

Conditions in the fire evidence

These describe tested or rated plant material. They are not horticultural maintenance instructions.

Where its sources say to plant it

Placement rules below use each source's own distances or named zones, tied to its rating. They are not interchangeable with the directory's current Zone 0 guidance.

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.
