|phenology=Flowering Mar–Jun; fruiting Apr–Jul.
|habitat=Sandy and rocky soil, prairies, oak savannas, oak woodlands, disturbed areas (pastures, roadsides), often locally moister sites
|elevation=0–500 m
|distribution=Ont.;Ark.;Iowa;Kans.;N.Y.;Okla.;S.C.;Tex.
|discussion=<p>The eastern records (Ontario, Iowa, Massachusetts, New York, and South Carolina) all appear to represent adventives or non-persistent waifs. A record from Maryland (J. B. S. Norton and R. G. Brown 1946) is plausible; no specimen is known to the author.</p>
