Separate evidence questions, never one approval badge

Set a ZIP to compare this record with state distribution, native range, USDA hardiness, and invasive records.

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
5 source placement records; source schemes remain separate.
Evidence regions
Colorado / Rocky Mountain Front Range; Maryland, New Jersey, and West Virginia; OR/WA/ID; Oregon (Willamette Valley); Pacific Northwest (Oregon / Washington / Idaho); Yavapai County, Arizona; southern Idaho / Intermountain
Maintenance
No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 8 scopes across 6 cited fire sources
  • Ignition-Resistant Landscape Plants (Fact Sheet 6.305) · Official scoped edition
    • CO; partial normalized coverage · 2025-07-01

      Colorado State University Extension and the Colorado State Forest Service publish Fact Sheet 6.305 for Colorado's WUI and varied ecosystems. FireApproved exposes all 114 exact source owners at Colorado publication scope while retaining score, elevation, water, and Idaho-carrier lineage. Publication scope is not suitability for every Colorado site or zone.

  • Fire Resistance of Plants Master Database · Official scoped edition
    • Southern Idaho (ID footprint); partial normalized coverage · 2013-11-08

      The official database labels itself "For Southern Idaho" and describes Idaho residents at the urban-rangeland interface. FireApproved publishes 419 existing plant owners that cite its scored rows. This bounded Southern Idaho scope is regional context, not statewide coverage or a conclusion that the score transfers unchanged to every Idaho site.

  • Firewise Landscaping Plants (Maryland, New Jersey, and West Virginia editions) · Official scoped edition
    • MD; partial normalized coverage · 2015-01-08

      Maryland Forest Service says the list contains plants that can be grown in Maryland and identifies Maryland natives. FireApproved publishes 169 exact source owners from the 180 printed rows; an unrepresentable form and duplicate-owner rows are not broadened. The list calls itself non-comprehensive and does not establish suitability for every Maryland site.

    • NJ; partial normalized coverage

      New Jersey DEP publishes a state edition saying the listed plants can be grown in New Jersey and are relatively resistant to fire. Its same 180 printed taxon occurrences map to the 169 conservative owners already normalized for the template family. The list is non-comprehensive and does not establish suitability for every New Jersey site or override the Pinelands Commission's separate placement and fuel-break rules.

    • WV; partial normalized coverage · 2026-08-26

      West Virginia Division of Forestry publishes a state edition saying the listed plants can be grown in West Virginia and are relatively resistant to fire. Its same 180 printed taxon occurrences map to the 169 conservative owners already normalized for the template family. The list is non-comprehensive and provides no comparative or site-specific rating.

  • 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
2 applicable cited hardiness statements overlap but have different boundaries; compare each complete source row.

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.

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.
