These are glacier lilies (Erythronium grandiflorum). During the late spring and summer, the open areas up at Logan Pass in Glacier National Park are rich with them.
These are a species of forget-me-nots, but I couldn't tell you which one. They're pretty, though.
Orange honeysuckle (Lonicera ciliosa). This particular vine graces a tree situated at the edge of my driveway. I can look out at it from my kitchen window.
These are queencups (Clintonia uniflora), also known as beadlilies. They grow in shady places, and in late spring and early summer they can be found peeking out from the underbrush. During the summer I see these all over when I go for walks.
Red (and one white) clover blossoms (Trifolium pratense) peep out from the foliage.
These are Engelmann asters (Aster engelmannii), which bloom all over the fields and roadsides in the late spring and early summer.
These are blossoms of common blue-eyed grass, which are miniature versions of the iris family (Sisyrinchium idahoense).
These are all different kinds of columbines (Aquilegia genus). They come in a variety of colors, from white to crimson to dark blue. They're a forest flower, but I most often find them alongside old sheds or whatnot.
These blossoms are silky lupines (Lupinus sericeus), which are a member of the pea family, believe it or not. They're a marvelous sight to behold when they spread across a wide stretch of meadow. Many of these were found along the roadsides at Glacier National Park.
