Oceanspray is rated fire resistant, with favorable Northwest guidance that includes maintenance requirements and a British Columbia research caution.
Oregon State puts Holodiscus discolor among deciduous shrubs in its fire-resistant planting guide. Most plants recommended there need some watering through Oregon's dry summer, and the guide calls for keeping them healthy. The favorable listing describes a cared-for landscape choice rather than making irrigation and upkeep irrelevant.
King County includes oceanspray in its shrub list for the Puget Sound Basin. The joint Oregon, Washington and Idaho extension publication also recommends the species, while Oregon State's Willamette Valley profile gives a more specific growing-region context. These sources offer consistent practical support for selecting the shrub.
FireSmart BC preserves a qualification alongside that agreement. Oceanspray appears on its fire-resistant chart with a request for further research. For a gardener, the useful result is a favorable recommendation with both the Oregon care advice and the British Columbia research flag attached. Neither requires treating the plant as an unconditional barrier to fire.

1. Fire evidence and conditions
Fire evidence
Fire-resistant — location does not change the cited classification.
King County's current wildfire page links this list for the Puget Sound Basin. FireApproved publishes 82 exact source owners as basin context, not statewide Washington guidance or a site-specific recommendation.
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.
The October 2023 joint Pacific Northwest Extension publication explicitly names Oregon, Washington, and Idaho and publishes more than 150 plant profiles. FireApproved has normalized 155 exact plant records from the source; publication scope does not assert that every listed plant suits every site within the three states.
Eastern Washington (WA footprint); partial normalized coverage
Washington DNR publishes the guide for Eastern Washington and says it compiles plants from other Firewise documents that are likely to thrive there. FireApproved publishes 46 exact owners only as eastern Washington context. The rows are corroborative, not empirical or statewide.

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.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
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.
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.

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.
“Fire-Resistant Plant Materials for Oregon”
· condition: green
Holodiscus discolor (Oceanspray) is listed under “Shrubs—deciduous”. The guide says most listed plants require some irrigation during Oregon's dry summer months and must be maintained in a healthy condition.
