Blue-flowered penstemons. Mt. Harrison.
Wikipedia - "A wildflower (or wild flower) is a flower that grows in the wild, meaning it was not intentionally seeded or planted. Yet 'wildflower' meadows of a few mixed species are sold in seed packets. The term 'wildflower' has been made vague by commercial seedsmen who are interested in selling more flowers or seeds more expensively than when labeled with only its name and/or origin. The term implies that the plant probably is neither a hybrid nor a selected cultivar that is in any way different from the way it appears in the wild as a native plant, even if it is growing where it would not naturally."
