|discussion=<p><i>Penstemon venustus</i> is known from the Snake River Plateau in west-central Idaho, northeastern Oregon, and southeastern Washington and is naturalized in Lassen County, California. E. C. Neese and N. D. Atwood (2003) reported <i>P. venustus</i>, apparently introduced, from Duchesne County, Utah. E. Heitz (1927) reported a chromosome number of 2n = 14–16 for <i>P. venustus</i>; that count conflicts with all other reports for <i>P. venustus</i>.</p>
