Western Wallflower/Erysimum asperum
The genus Erysimum is a Greek word that refers to the Bittercress plant (another member of the mustard family). The base is the Greek word, eryso, meaning 'to cure' or to 'ward off'; thus referring to the curative aspects of certain plants of this genus. The species asperum means 'rough', referring to the dense forked hair on the plant. The term 'wallflower' is generally thought to refer to several of the old world plants that resemble this species and were frequently found growing on old walls.

I took these shots at Rough and Ready Creek in May and June, they are such a lovely bright spot in the area, catching your eye and asking yourself, what is that beauty called?
