Western Wallflower (Erysimum asperum)
Description
Erysimum asperum is very similar to Erysimum capitatum. E. asperum is found on the plains, but it's range continues to higher elevation and overlaps with the range of E. capitatum. Weber describes E. asperum as having gray-pubescent seed pods, compared to greener, smoother seed pods on E. Capitatum.
