1. Fire evidence and conditions

Fire evidence
Fire-resistant — 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
Alaska; Michigan / Great Lakes; Ohio / Midwest; Oregon; Tasmania, Australia; eastern US; southern Idaho / Intermountain
Maintenance
No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 4 scopes across 4 cited fire sources
  • Protect Your Home from Wildfire — Fire Resistant Vegetation and Landscaping · Official scoped edition
    • AK; partial normalized coverage · 2005-04-27

      Alaska Division of Forestry opens with the wildfire threat to Alaskans and publishes Alaska firewise-landscape examples. FireApproved publishes 58 exact source owners from its 60 taxon entries and holds the taxon-free fern label. State publication scope does not establish suitability for every Alaska climate, site, or home-ignition-zone placement.

  • 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.

  • Wildfire-resistant Landscape Plants for Michigan (Extension Bulletin E2948) · Official scoped edition
    • MI; partial normalized coverage · 2007-01-01

      Michigan State University Extension Bulletin E2948 is explicitly a list of wildfire-resistant landscape plants for Michigan and includes a Michigan-native field. FireApproved publishes 221 exact GBIF owners from 226 represented source rows and holds 15 complex or non-exact rows. This dated publication scope is not a current site-suitability determination.

  • Firewise Landscaping (OSU Extension Bulletin 921) · Official scoped edition
    • OH; partial normalized coverage · 2006-03-01

      Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.

2. Why this plant is relevant here

State distribution
Documented in AK, CA, CO, CT, DC, DE, IA, ID, IL, IN, MA, MD, ME, MI, MN, MT, ND, NH, NJ, NY, OH, OR, PA, RI, SC, UT, VT, WA, WI, WV, WY.
Native range
No current cited or legacy state native range is normalized.
Introduced / established
33 sourced range or established records; set a location to match them. This is not an invasive warning.
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
1 legal-list record; set a location to match exact scope.
Seed-list status
Set a location to compare the separate state noxious-weed seed layer.
Reported invasive here
2 ecological invasive reports; set a location to distinguish exact from regional context.
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.

Native and introduced range evidence

These are exact U.S. botanical-area records from the cited range source. Native and introduced describe biogeographic relationship, not fire performance or planting approval. Doubtful and extinct rows stay visible but do not count as current presence.

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.
