1. Fire evidence and conditions

Fire evidence: Highly flammable — 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: 5 source placement records; source schemes remain separate.
Evidence regions: Butte County and California's North State; California; Marin County, California; OR; Oregon; South Carolina; South Florida; Yavapai County, Arizona; eastern US
Maintenance: No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

Typed publication scope: 6 scopes across 6 cited fire sources

Landscaping to Reduce Wildfire Risk: South Florida Edition · Official scoped edition
- South Florida (FL footprint); partial normalized coverage · 2013-04-09
  Florida Forest Service labels this publication the South Florida Edition. FireApproved publishes eight exact owners from its explicit narrative hazard callouts as South Florida context. It is not a statewide ranked list and its source-wide guidance is not projected onto unnamed plants.
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.
Defensible Space Landscaping in the Urban/Wildland Interface: A Compilation of Fire Performance Ratings of Residential Landscape Plants · Official scoped edition
- CA; partial normalized coverage · 1997-07-01
  The UC Forest Products Laboratory says the guide covers properties of common California landscaping plants and was prepared for California fire agencies. FireApproved publishes 130 exact owners at historical California publication scope. The report is a 1997 compilation, not a current endorsement, site rating, or independent test of every row.
Landscaping Can Be Attractive & FIREWISE (Fire Smart Plant List for SC) · Official scoped edition
- SC; partial normalized coverage
  South Carolina Forestry Commission publishes this explicitly as its Fire Smart Plant List for South Carolina. FireApproved publishes 63 exact genus owners from 72 unique common-name labels; unsafe common-name mappings and duplicates are not broadened. The brochure calls the list non-inclusive and does not establish species-level or site-specific suitability.
Firewise: Fire Resistant Plants · Official scoped edition
- Butte County and California's North State (CA footprint); partial normalized coverage · 2023-06-02
  UC Master Gardeners of Butte County frame the article for North State residents. FireApproved publishes only the two taxonomically exact owners from its prose examples and keeps them as northern California regional context. Generic maples, broom, Echinacea, creeping thyme, and Oregon grape remain held rather than being projected to species. The article is not a statewide list or site clearance.
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 CA.
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: Only uncertain or inapplicable hardiness rows are cited; no primary zone is projected.

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.

Eastern United States Fire Performance Plant Selector · record eucalyptus-spp · 2016-wayback · as of 2026-08-26

Source prints 7 · single-value meaning unresolved · whole zone precision · source stated

Source taxon: Eucalyptus spp. · exact match.

Source location: Cold Hardiness Zone field in the recovered selector record.

Not used for comparison: The recovered selector prints one Cold Hardiness Zone value but does not define it as a minimum threshold or a one-zone range.

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.
