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
- 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
- 2 source placement records; source schemes remain separate.
- Evidence regions
- Louisiana; Maryland, New Jersey, and West Virginia; Ohio / Midwest; southern Idaho / Intermountain
- 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 OH.
- Native range
- The legacy compatibility field lists OH in native range; its field-level source was not retained.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- 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
- 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.

The evidence
Recommends (2)
-
Firewise Landscaping (Hammond Research Station)
“recommended for firewise landscaping in Louisiana”
-
Firewise Landscaping Plants (Maryland, New Jersey, and West Virginia editions)
“relatively resistant to fire”
Listed as Rudbeckia spp. (Coneflower). The source says listed species exhibit stronger resistance to ignition by wildfires. Source comments: Many native and cultivated species
Mid-scale / conditional (2)
-
Firewise Landscaping (OSU Extension Bulletin 921)
“M flammability”
Tolerates full sun; variable moisture regimes; some adapt to mass planting.
