Fire-resistant. Recommended by 3 independent evidence lineages with no objection on record across 7 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.

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

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.

Winged elm has both native and introduced occurrences documented in range evidence. That split is kept visible so the geographic records are not collapsed into a single undifferentiated range statement.

Every directional row supports the on-list result for Ulmus alata. The sources include a placement marked Firewise, low-flammability entries, and a guide for the Willamette Valley; their individual wording and provenance remain in the evidence table.

The three minimum-hardiness assertions are shown in hardiness evidence. They print 5, 6, and 5a, with the first marked uncertain and the latter two applicable, so readers can see both the values and their different evidence status.

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.
Firewise Landscaping (OSU Extension Bulletin 921) · Official scoped edition
- OH; partial normalized coverage · 2006-03-01
  Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio 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.
Virginia Firescapes — Firewise Landscaping for Woodland Homes (430-300) · Official scoped edition
- VA; partial normalized coverage · 2009-04-15
  Virginia Cooperative Extension's publication opens with Virginia wildfire conditions, identifies its Virginia Firewise Landscaping Task Force, and labels plants native to Virginia. FireApproved publishes 306 exact source owners. Publication scope does not establish parcel suitability or current endorsement of this archived 2009 list.

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.
