Separate evidence questions, never one approval badge

Set a ZIP to compare this record with state distribution, native range, USDA hardiness, and invasive records.

A genus split is not a placement verdict. Set a ZIP to read the local documented split.

1. Fire evidence and conditions

Fire evidence
Highly flammable — location does not change the cited classification.
Fire-performance conditions
No test or rating condition is normalized.
Fire ecology context
No section-reviewed fire-ecology context is normalized.
Placement evidence
1 source placement record; source schemes remain separate.
Evidence regions
Ashland, Oregon; Global
Maintenance
No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 1 scope across 1 cited fire source
  • Prohibited Flammable Plants (Ashland Municipal Code 9.04) · Official scoped edition
    • City of Ashland (OR footprint); partial normalized coverage · 2026-08-26

      This is a City of Ashland adoption fact, not statewide Oregon guidance or an experimental flammability result. FireApproved publishes 24 taxonomy-safe owners as city-level regulatory context. It applies to new planting and propagation within 30 feet of structures, including structures on adjacent lots; it is not projected as a blanket removal order for every established listed plant.

2. Why this plant is relevant here

State distribution
Documented in AZ, CA, CO, ID, MA, MT, ND, NE, NM, NV, OR, SD, UT, WA, WY.
Native range
Current cited native range in AZ, CA, CO, ID, MT, ND, NE, NM, NV, OR, SD, UT, WA, WY.
Introduced / established
1 sourced range or established record; set a location to match them. This is not an invasive warning.
USDA hardiness
Documented minimum 2b; no upper limit is documented.

3. Legal, ecological, and broader status

Legal-list status
Set a location for an exact legal-list result; source silence is not clearance.
Seed-list status
Set a location to compare the separate state noxious-weed seed layer.
Reported invasive here
No ecological invasive report is normalized; that does not prove noninvasiveness.
Broader regional context
Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
Federal context
Federal designations remain separate from state legal-list results.
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.

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.

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.
