Your local evidence lens
Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Highly flammable — 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
- Australian Capital Territory, Australia; Global; eastern US
- 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 DC, DE, MD, NJ, OH, PA, WV.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- USDA hardiness
- Only uncertain or inapplicable hardiness rows are cited; no primary zone is projected.
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.
