Japanese cunninghamia carries an avoid recommendation. The Cunninghamia lanceolata pack is limited evidence on the evidence table, and it retains 1 ecological invasive report as a distinct status fact. The direction, source depth, and ecological context therefore remain visible without being collapsed into one claim.
Same-form alternatives are organized under related plants, while hardiness evidence keeps its own role in the record. The genus index widens the browsing path, not the accepted source pack for this species. This structure lets a reader compare form, inspect hardiness, or browse Cunninghamia while leaving the avoid result and single ecological report with C. lanceolata.
Only uncertain or inapplicable hardiness rows are cited; no primary zone is projected.

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 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 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.
Strange flat green to blue needles born in a single plane. Very pointed needles that are held on to tree after they have died. Suckers readily forming impenetrable clumps.
