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: 9 source placement records; source schemes remain separate.
Evidence regions: Alabama; Arkansas; British Columbia; Catalonia, Spain; Global; Japan; Maryland, New Jersey, and West Virginia; Michigan / Great Lakes; NC; North Carolina; North Carolina / southeastern US; Ohio / Midwest; Tennessee; Virginia / Mid-Atlantic; eastern US; southern Idaho / Intermountain
Maintenance: No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

Typed publication scope: 10 scopes across 8 cited fire sources

Firewise Landscaping for Woodland Homes · Official scoped edition
- AL; partial normalized coverage
  The Alabama Forestry Commission's five-page AFC-FP-04 booklet is an Alabama publication and contains 31 printed suggested or fire-prone plant occurrences. FireApproved publishes 27 exact species or genus owners and holds one infraspecific form plus two named cultivars; this historical source scope does not establish current site suitability for a particular Alabama property.
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.
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.
Fire-Resistant Landscaping in North Carolina (AG-874) · Official scoped edition
- NC; complete normalized coverage · 2025-03-26
  The complete three-table AG-874 plant list is explicitly for North Carolina and contains 202 low-, medium-, or high-flammability rows. FireApproved accounts for all source rows under its strict taxonomy and lineage rules; source scope does not establish local suitability at a particular North Carolina site.
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.
Landscaping Guidelines to Protect Your Home from Wildfire (SP685) · Official scoped edition
- TN; partial normalized coverage · 2006-10-24
  University of Tennessee Extension SP685 is Tennessee landscape guidance and publishes 78 represented plant owners. Most table rows are a carrier of Virginia Firescapes rather than an independent rating; Tennessee source scope does not change that lineage or establish site suitability.
Virginia Firescapes — Firewise Landscaping for Woodland Homes (430-300) · Official scoped edition
- VA; partial normalized coverage · 2009-04-15
  Virginia Cooperative Extension's publication opens with Virginia wildfire conditions, identifies its Virginia Firewise Landscaping Task Force, and labels plants native to Virginia. FireApproved publishes 306 exact source owners. Publication scope does not establish parcel suitability or current endorsement of this archived 2009 list.

2. Why this plant is relevant here

State distribution: Documented in AL, AR, CT, DC, DE, FL, GA, IA, IL, IN, KY, LA, MA, MD, MI, MO, MS, NC, NJ, NY, OH, PA, RI, SC, TN, TX, VA, VT, WV.
Native range: Current cited native range in AL, AR, CT, DC, DE, FL, GA, IL, IN, KY, LA, MA, MD, MI, MO, MS, NC, NJ, NY, OH, PA, RI, SC, TN, VA, VT, WV.
Introduced / established: 2 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: 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.

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.

Mid-scale / conditional (2)

Fire Resistance of Plants Master Database — Idaho Firewise (BLM + College of Western Idaho + Idaho Botanical Garden) · original source Primary evidence Field program lineage: idaho-tree

“fire-resistance score 4 of 10” · score 4 (idaho-0-10)
Tree fire-protection classification in Hito to Shinrin (人と森林) — Kyoritsu Shuppan; table reproduced by Kagoshima Prefecture · Hito to Shinrin (1982), Table 10-2; Kagoshima web reproduction · original source Primary evidence Expert-curated lineage: independent (root of Japanese municipal fire-protection tree lists)

“中” · score 2 (tadaki-kira-fire-protection-power-0-3)

Table 10-2 prints ユリノキ in the medium fire-protection-power class. The Kagoshima reproduction says highly fire-protective trees can slow spread, promote upward dispersal of heat and smoke, and intercept flying embers.
