Parry's Primrose-Primula parryi

This striking magenta flower found at higher elevations and often near water is Parry's primrose (Primula parryi), a member of the Primrose Family (Primulaceae). 

Most of them have finished flowering for this year, leaving the leafy vegetation behind.

But I looked all around and managed to find a few flowers still hanging on. This flower lends so much color to the sub-alpine and alpine scenery. It also stands out because it is so large compared to much of the higher elevation vegetation, much of which has shrunken in size to deal with the harsher growing conditions.

Threenerve Goldenrod-Solidago velutina

Seeing goldenrod in flower is bittersweet--it's one of those flowers that appears at the end of summer, and you know that it won't be too long until the cold creeps in. This species grows in dry areas and is Threenerve Goldenrod (Solidago velutina), a member of the Sunflower Family (Asteraceae). It's native to the western United States.

Brook Saxifrage-Saxifraga odontoloma

Growing next to a stream I noticed leaves that were a notched semi-circle with even dentations all around the edge. Rising from these leaves was a slender stalk and delicate, small flowers. This was brook saxifrage (Saxifraga odontoloma), also called streamside saxifrage. It is native to western North America.

The flowers have five petals with a two-beaked pistil and ten reddish anthers.

Largeleaf Avens-Geum macrophyllum

This large plant growing next to a stream was a little bit of a mystery at first, because it had already flowered and only had strange looking fruits on it. The leaves were large and split in three leaflets. A little searching showed it was a member of the Rose Family (Rosaceae) called largeleaf avens (Geum macrophyllum). It's native to western and northern North America.

Flowers appear in June and July, but by August only the seed is left.

Unless you get lucky and catch a few petals still clinging on!
