Trillium viridescens Nutt. Sessile Least Concern Apparently Secure (G4) US: AR, KS, LA, MO, OK, TX
Ozark Green Trillium (Trillium viridescens) occurs from southern Missouri and southeast Kansas to extreme eastern portions of Texas. The species is locally common throughout its range on rich clay soils on rocky bluffs, talus slopes, and floodplains. The population trend of the species is not currently known. Threats that may impact the species include herbivory pressure from overabundant White-tailed Deer, logging, habitat degradation caused by feral Pigs, and invasive plants including Burning Bush and Bush Honeysuckle. Because the species is locally common across a broad distribution, it is at a low risk of extinction.
