Prunus angustifolia · Rosaceae · all Prunus records · Wikipedia

Fire-resistant. Recommended by 2 independent evidence lineages with no objection on record across 5 cited sources. This status is computed from the cited evidence by the published rule, never hand-assigned. The page keeps its cited source rows visible for readers and separates each evidence channel from the computed result on this record.

▲ North Carolina's Bardon 2005 list ▲ Fire-resistant Landscape Plants for the Willamette Valley ◆ the Eastern US Fire Performance Plant Selector

Computed class: Fire-resistant (consensus) — derived from the cited evidence by a published rule, never hand-assigned. Each chip above is one independent primary-evidence lineage and its direction. No plant is fireproof; condition and placement govern. Zone 0 is hardscape regardless.

Fire-Resistant Landscaping in North Carolina (AG-874) · Official scoped edition
- NC; complete normalized coverage · 2025-03-26
  The complete three-table AG-874 plant list is explicitly for North Carolina and contains 202 low-, medium-, or high-flammability rows. FireApproved accounts for all source rows under its strict taxonomy and lineage rules; source scope does not establish local suitability at a particular North Carolina site.
Fire-resistant Landscape Plants for the Willamette Valley (EM 9103) · Official scoped edition
- Willamette Valley (OR footprint); partial normalized coverage · 2015-02-01
  OSU Extension says EM 9103 highlights fire-resistant plants that thrive under Willamette Valley growing conditions. FireApproved publishes 172 exact owners only as valley context. The guide shares the PNW 590 lineage and is not a second independent vote or statewide site clearance.

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.

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.

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.

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.
