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: 4 source placement records; source schemes remain separate.
Evidence regions: Maine; Maryland, New Jersey, and West Virginia; Ohio / Midwest; eastern US; northeastern Minnesota
Maintenance: No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

Typed publication scope: 6 scopes across 4 cited fire sources

Landscaping for Wildfire Defensible Space in Northeastern Minnesota (Firewise) · Official scoped edition
- Northeastern Minnesota (MN footprint); partial normalized coverage · 2017-01-01
  Dovetail applies the UF/IFAS flammability key to northeastern Minnesota natives and publishes placement for 38 exact source owners. FireApproved exposes those rows only as northeastern Minnesota regional context and preserves the 3-to-30-foot versus beyond-30-foot source placement.
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.
Maine fire-resistant plant list · Official scoped edition
- ME; partial normalized coverage · 2013-10-23
  Maine Forest Service presents a partial list for landscaping 30-100 feet from a structure. FireApproved publishes only 39 unique exact current/accepted matches plus Rhus typhina from the source's explicit parenthetical; unresolved, abbreviated, misspelled, absent, and duplicate-owner rows remain held.
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 AL, CT, DC, DE, GA, IA, IL, IN, MA, MD, ME, MI, MN, NC, ND, NH, NJ, NY, OH, PA, RI, TN, VA, VT, WI, WV.
Native range: Current cited native range in CT, DE, GA, IA, IL, IN, MA, MD, ME, MI, MN, NC, ND, NH, NJ, NY, OH, PA, RI, TN, VA, VT, WI, WV.
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.

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.

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.

Eastern United States Fire Performance Plant Selector: Landscape Zone 2 — 5–10 ft from the structure; maintained lawn or fuel breaks, with easily ignited evergreens avoided [Fire Performance Plant Selector landscape zone] (mid-scale rating)
Landscaping for Wildfire Defensible Space in Northeastern…: plantable 3-30 ft from a building [Dovetail Partners planting distance] (with its recommendation)

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.
