Baseline 66; additional insect credit +0. Rarity adjustment -5 using the NC rule (unranked: −5; final score floor: 5). Missing records do not establish zero ecological use.

County occurrence is not proof of native range or yard suitability. A missing record does not establish absence.

Native-status evidence

Combined TN–KY atlas flag: Y. A regional flag alone does not settle Tennessee native status.

Combined-source assessment

Native to Tennessee (state-specific source)

A TN-specific UT native-guide page or an exact entry in the Tennessee rare-plant list supports a direct source claim. Otherwise, TN occurrence plus an atlas native flag and exact-name native evidence from NC flora or USDA L48 supports a provisional state inference. No one regional claim or occurrence alone establishes TN nativity; NC and L48 claims retain their actual scopes.

UT Tennessee Smart Yards native-plant guide: native (TN). Native Region: Only in Davidson, Wilson, Rutherford, Rhea, Meigs and Bradley counties

TN–KY Plant Atlas: native (TN–KY).
