Common names:
Mountain meadow cinquefoil, vari-leaf cinquefoil, blueleaf cinquefoil
Scientific name:
Potentilla glaucophylla
Range:
The Rocky Mountain states, all states to the west, and part of the northern Great Plains
Habitat:
Meadows, dry slopes, open woodland, grassland; from near sea level to 11,500 feet
Leaves:
Stalked, mostly basal, blue-green, divided into 5 to 7 toothed leaflets, the largest up to 2.5 inches long
The green or reddish stems of potentilla glaucophylla rise up at a low angle, and bear leaves mostly at the base; these are bluish-green in color, palmately divided into coarsely-toothed leaflets. Leaves are attached by stalks of up to five inches which, like the stems, have a sparse to moderate covering of hairs, usually appressed. Leaves are generally divided into five or six leaflets (occasionally seven), which are lined by teeth, divided up to half way, or more, to the midvein. There are usually between one and three teeth per edge, less often up to five. Both leaf surfaces may have a light hair covering. Stems usually have one or two leaves, smaller and less divided.
The inflorescence is an open cluster at the top of the stems, usually containing up to ten flowers, but sometimes twice this number. Individual flower stalks are up to 2 inches long. Flowers have five narrow bractlets and five longer, wider, pointed sepals, all dark green and hairy, above which are five much wider, yellow, obovate petals, around half an inch long. Petals have a shallow notch at the tip. At the center are around 20 yellow stamens and a similar number of green carpels. The base of the stamens is reddish.
Var glaucophylla has teeth cleft to less than half way to the midvein, while var perdissecta has teeth cleft to more than half way.
