Arrowleaf Balsamroot, Balsamorhiza sagittata

Common East of the Cascades, this sunflower relative grows in abundance on Kamiak Butte.

Palmate Coltsfoot, Petasites palmatus

This native perennial produces flowering stems that are present before leaves appear.

Windflower, Anemone piperi

This rather unassuming flower was found growing on Kamiak Butte in Eastern Washington.

Stink Currant, Ribes bracteosum

The crushed leaves of this plant have a 'skunky' smell. The flowers give way to edible blue-black berries.

Small-Flowered Buttercup, Ranunculus uncinatus

Very small flowers, only about 0.2" across, are found on this native perennial that grows in shady, moist soil.

7-7-2012 update.  Finally found one with all 5 petals intact:

Upland Larkspur, Delphinium nuttallianum

Unfortunately, when I visited Kamiak Butte, these pretty flowers had not yet completely opened.

Heart-Leaved Twayblade, Listera cordata

Not many flowering plants have green flowers, but this member of the Orchid family is an example.

Found a small patch of these Orchids on Bells Mountain.
