Memorial rose stays limited evidence in the source table. Its sole directional row considers the shrub wildfire-resistant and recommends it for Michigan's climate.
The same source gives Rosa wichuriana an applicable 5–8 hardiness range. A separate temperature measurement maps -23°F to an applicable 4b minimum; both interpretations remain in hardiness evidence without being collapsed into one band.
One ecological report records introduced-established status on the accepted-name basis. It remains outside the fire tally. The cited recommendation retains its regional scope, while the single fire row leaves the on-list page evidence-limited.

Typed publication scope: 1 scope across 1 cited fire source
Michigan State University Extension Bulletin E2948 is explicitly a list of wildfire-resistant landscape plants for Michigan and includes a Michigan-native field. FireApproved publishes 221 exact GBIF owners from 226 represented source rows and holds 15 complex or non-exact rows. This dated publication scope is not a current site-suitability determination.

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.
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.
Minimum 4b · no upper limit documented · half zone precision · derived containing band
Exact source measurement: -23°F; mapped only to its containing half-zone.
Source taxon: Rosa wichuriana · source identifier match.
Source location: PlantCharacteristics record 90962, Temperature, Minimum (°F).
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.
