Growing conditions

Full sun, medium to dry moisture, adapted to a wide range of soils including clay, moderately acid to neutral pH. 1-3 feet height, blooms in summer, yellow/orange flowers, spreads slowly by re-seeding.

Native Region: Occurs only in two counties – Campbell and Davidson UT Smart Yards source

Native-status evidence

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

Combined-source assessment

Native status: sources disagree

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: Occurs only in two counties – Campbell and Davidson

USDA PLANTS: native (L48). CAN:N L48:N

TN–KY Plant Atlas: introduced (TN–KY).
