About plant names...

Blue toadflax is pretty easy to miss. The foliage is thin, thinner than grass blades, and the flowers are diminutive, atop thin stems. From a distance, a colony of blue toadflax resembles a low-lying cloud of blue mist. It is pretty cool when you take a closer look at it.

Identification: Up to 24" (60 cm) in height, though it is sometimes bent under its own weight. Flowers are blue, and ¼-½" (6.3-12 mm) long. They are “bilaterally symmetrical,” that is, if you cut them down the center, the halves are mirror images. There are two petals on top, and three larger ones on the bottom, with a white patch in the center. Stems may be green or reddish-green. Leaves are less than ⅛" (3.2 mm) wide and up to 1½" (3.8 cm) long.
