Feather Reed Grass carries an avoid result in the evidence table. Its sole source marks the plant very highly flammable and places it in planting positions beginning at 2 and continuing through 3 or beyond.

The same 2006 row says the grass tolerates sun and remains upright through winter. With no second directional source, the record stays limited evidence; those landscape notes do not change the avoid direction.

related plants retain the same-form comparison path, while the genus page keeps the taxonomic route. The cited row remains available in the source table for its placement and wording.

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.

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.
