Loebner's magnolia is rated fire resistant by both published assessments.
The USDA Forest Service’s eastern plant selector gives it the best of its four ratings, while Michigan State University Extension includes it among wildfire-resistant plants recommended for Michigan’s climate.
The agreement is useful because the sources approach the question differently. The Forest Service and state Firewise programs use a four-level scale running from Firewise to Not Firewise. Michigan State uses an expert-curated list: inclusion means the plant is recommended. Both reach the favorable result without any conflicting assessment.
Loebner’s magnolia is a tree in the magnolia family, growing to about 20 feet at maturity in part sun. It is hardy to USDA zone 5a, which helps define where it can be grown. Taken together, the eastern regional rating and Michigan recommendation make a clear case for treating Loebner’s magnolia as a fire-resistant landscape choice where its climate needs are met.

1. Fire evidence and conditions
Fire evidence
Fire-resistant — location does not change the cited classification.
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.
Source prints 5 · single-value meaning unresolved · whole zone precision · source stated
Source taxon: Magnolia x loebneri · exact match.
Source location: Cold Hardiness Zone field in the recovered selector record.
Not used for comparison: The recovered selector prints one Cold Hardiness Zone value but does not define it as a minimum threshold or a one-zone range.

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.
Eastern United States Fire Performance Plant Selector: Landscape Zone 3 — 10–30 ft from the structure; thin vegetation, remove debris, and minimize plant massing [Fire Performance Plant Selector landscape zone] (with its recommendation)
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.
