Wild Blue Flax (Linum lewisii)
Location: Windy Saddle Park, Jefferson County, Colorado, USA
From late spring until the end of summer, this wildflower can be found along roadsides and in meadows in much of the western United States. The flowers are short-lived. They bloom just after dawn, and drop their petals later in the day. Fortunately, the blossoms are replaced each day throughout the season.
The species name honors Capt. Meriwether Lewis, of the Lewis and Clark expedition. He is said to have noted the presence of this wildflower in the northern Idaho territory.
