Listed in Tennessee’s rare-plant reference. Use nursery-propagated plants; conservation status is separate from this ecological score.

Strong

Tennessee · provisional Quercus Score

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

Tennessee scoring method and limits

Insect resources, birds and habitat

Caterpillars	17 recorded species on the genus Host genera of native Lepidoptera recorded in Tennessee; host association and range overlap, not confirmed local feeding.
Bees	20 recorded species on the genus Southeastern North America
Specialist bees	0 recorded species on the genus Eastern North America
Birds	2 recorded species on the genus North America
Structure	Forb/herb

Baseline 67; 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.

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

Part to full shade, moderately wet to moderately dry moisture level, prefers rich loam soil, circumneutral pH. 8 inches height, blooms in summer, white flowers.

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.
