The guide is authored for the Sun City Texas community in Georgetown. FireApproved publishes 142 exact owners only as community-level context. It is an archived HOA exhibit with unknown rating lineage, not a current statewide Texas source or an independent Tier 1 determination.

Texas A&M AgriLife Extension publishes this page through its Travis County horticulture program. FireApproved publishes 56 exact owners and retains the source's zone and warning conditions. This is county/Austin regional context, not a second statewide Texas table or site clearance.

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.
Source location: PlantCharacteristics record 24073, Temperature, Minimum (°F).
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.
Eastern United States Fire Performance Plant Selector: Master Plant DB row 866 [lwf-2024-fps-carrier] (with its avoid rating)
Firewise Landscaping: Perennials [Travis County Firewise page sections] (with its avoid rating)
Firewise Plant Guide: Ornamental Grasses [Sun City plant-table sections] (with its avoid rating)
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.
Listed as Deergrass — Muhlenbergia rigens. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
“Plants to Avoid for Zone 1 (within 30′ of Structure)”
Listed as Muhly, Deer — Muhlenbergia rigens. The page says Zone 1 entries should be restricted to zones 2 or 3; all-zone entries are highly flammable due to volatile oils or growth habit.
The table rates Muhly, Deer — Muhlenbergia rigens high for flammability hazard, defined as the ease a plant can burn at high temperatures for a prolonged time.
