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
1 condition stated in cited fire-evidence rows.
Fire ecology context
No section-reviewed fire-ecology context is normalized.
Placement evidence
3 source placement records; source schemes remain separate.
Evidence regions
Colorado, California, and northeastern United States; Global; Lake Tahoe Basin, Nevada and California; Ohio / Midwest; Virginia / Mid-Atlantic; eastern US
Maintenance
No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 3 scopes across 3 cited fire sources
  • Home Landscaping Guide for Lake Tahoe and Vicinity (Ed. Bulletin 06-01) · Official scoped edition
    • Lake Tahoe Basin (CA, NV footprint); partial normalized coverage · 2006-01-01

      Nevada Division of Forestry and University of Nevada Cooperative Extension publish Bulletin 06-01 for the Lake Tahoe Basin and vicinity. FireApproved publishes 83 exact rated owners as basin context across Nevada and California. Rough estimates are not statewide or site ratings.

  • 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.

  • 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.

2. Why this plant is relevant here

State distribution
Documented in AZ, CO, DC, DE, ID, MA, MD, ME, NJ, NM, NV, OH, OR, PA, UT, WV, WY.
Native range
Current cited native range in AZ, CA, CO, ID, NM, NV, OR, UT, 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 3a; 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.

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.

Conditions in the fire evidence

These describe tested or rated plant material. They are not horticultural maintenance instructions.

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.
