Calculated with the same rules as North Carolina, using Tennessee host-range and conservation-rank inputs. Native-status evidence is shown separately.

Baseline 58; additional insect credit +0. Rarity adjustment -8 using the NC rule (unranked: −5; final score floor: 5). Missing records do not establish zero ecological use.

Native to Tennessee (state-specific source). Tennessee yard-fit calculations are not available yet.

Also available: North Carolina assessment. Both assessments use the same scoring rules with the evidence shown for each state.

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

Growing conditions

Full sun to light shade, wet to moderately wet moisture level, prefers mucky or slightly sandy soil but is tolerant of clay, very strongly acid to neutral pH. 2 feet height, spreads slowly by seed and moderately fast by rhizomes.

Native Region: Only occurs in 5 counties – Obion, Stewart, Montgomery, Lewis and Rhea UT Smart Yards source

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 occurs in 5 counties – Obion, Stewart, Montgomery, Lewis and Rhea
