-->{{Treatment/Body
|phenology=Flowering spring (early Apr–mid May).
|habitat=Deciduous forests, usually quite rich, on banks, bluffs, talus slopes, floodplain alluvium, with cane (Arundinaria) or on sloping banks just above normal flood levels in heavy, clayey soils, with common spring ephemerals
|elevation=100–400 m
|distribution=Ark.;Kans.;Mo.;Okla.;Tex.
|discussion=<p>Of conservation concern.</p><!--
--><p>J. D. Freeman (1975) considered that <i>Trillium viridescens</i> intergrades with <i>T. gracile</i> in northeastern Texas and stated that these putative intergrades produce purple petals, but purple-petaled forms also occur in Arkansas, far from the influence of <i>T. gracile</i>.</p>
