Poa cita carries keep away recommendation on poa cita. On poa cita, limited evidence next to poa cita on Poa cita. This is not one slogan for poa cita — Poa cita. On poa cita, avoid does not replace limited evidence for poa cita.

On poa cita, Poa cita also carries same form alternatives for poa cita.

Use evidence on poa cita for poa cita. The sourced rows remain on poa cita.

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.

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.
