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
Mixed evidence — 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
0 source placement records; source schemes remain separate.
Evidence regions
Global; New Zealand
Maintenance
No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.

2. Why this plant is relevant here

State distribution
Documented in CT, IL, MA, MD, ME, MI, MN, NH, NJ, NY, OH, OR, WI.
Native range
No current cited or legacy state native range is normalized.
Introduced / established
12 sourced range or established records; set a location to match them. This is not an invasive warning.
USDA hardiness
No hardiness value is normalized.

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
1 ecological invasive report; 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.

The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.

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.
