Separate evidence questions, never one approval badge

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: 2 source placement records; source schemes remain separate.
Evidence regions: Alaska; northeastern Minnesota
Maintenance: No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

Typed publication scope: 2 scopes across 2 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.
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.

2. Why this plant is relevant here

State distribution: Documented in AK, CO, CT, IA, ID, IL, IN, MA, MD, ME, MI, MN, MT, ND, NH, NJ, NM, NY, OH, OR, PA, RI, SD, VA, VT, WA, WI, WV, WY.
Native range: Current cited native range in AK, CO, CT, IA, ID, IL, IN, MA, MD, ME, MI, MN, MT, ND, NH, NJ, NM, NY, OH, PA, RI, SD, VA, VT, WA, WI, WV, WY.
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.

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.
