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
1 condition stated in cited fire-evidence rows.
Fire ecology context
No section-reviewed fire-ecology context is normalized.
Placement evidence
4 source placement records; source schemes remain separate.
Evidence regions
California; Catalonia, Spain; Global; Mediterranean southeast France; Michigan / Great Lakes; Ohio / Midwest; Southern California; Utah / Intermountain West; Valencia, Spain / western Mediterranean; eastern US
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

2. Why this plant is relevant here

State distribution
Documented in AL, AR, AZ, CA, CT, DC, DE, FL, GA, HI, ID, IL, IN, KY, LA, MA, MD, MI, MO, MS, NC, NJ, NY, OH, OR, PA, SC, TN, TX, UT, VA, WA, WV.
Native range
No current cited or legacy state native range is normalized.
Introduced / established
35 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
3 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.
