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 AL, AR, CA, CT, DC, ID, IL, IN, KS, KY, MA, MD, ME, MI, MO, NC, NJ, NM, NY, OH, OR, PA, RI, TN, UT, VA, WA, WI, WV.
Native range
No current cited or legacy state native range is normalized.
Introduced / established
33 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.

Evidence
6 cited sources
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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
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.
Guía de pirojardinería: suitable inside or outside the 25-metre maximum-risk zone [girona-2020-iuf-25m-suitability] (with its recommendation)
The fire risk of the plant groupings with Cistus in the a…: Table 1 [henaoui-2013-fresh-material-flammability] (with its avoid rating)
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.
Rosa canina is rated “MUY RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
