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
- 9 source placement records; source schemes remain separate.
- Evidence regions
- Alabama; Alaska; Arizona above 3,000 feet / interior Southwest; Black Hills, South Dakota; British Columbia; Marin County, California; Maryland, New Jersey, and West Virginia; Michigan / Great Lakes; Nevada / Great Basin; OR/WA/ID; Ohio / Midwest; Oregon; Pacific Northwest (Oregon / Washington / Idaho); South Carolina; Tennessee; Virginia / Mid-Atlantic; Yavapai County, Arizona; western WA

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.
