Prairie Cordgrass
Also known as
Cord Grass; Slough Grass
Listed in Tennessee’s rare-plant reference. Use nursery-propagated plants; conservation status is separate from this ecological 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 | 11 recorded species on the genus Host genera of native Lepidoptera recorded in Tennessee; host association and range overlap, not confirmed local feeding. |
| Bees | 0 recorded species on the genus Southeastern North America |
| Specialist bees | 0 recorded species on the genus Eastern North America |
| Birds | 1 recorded species on the genus North America |
| Structure | Graminoid |
Baseline 37; 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
Full to part sun, wet to medium moisture level, best grown in fertile loam but will tolerate sandy or rocky soil with consistent moisture, slightly acidic to alkaline pH. 6-8 feet height, blooms in June, yellow flowers, spreads aggressively by rhizomes.
Native Region: Scattered in 9 counties, occurring in all provinces except the Central Basin and Blue Ridge. 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: Scattered in 9 counties, occurring in all provinces except the Central Basin and Blue Ridge.
