Technical Name

• Potentilla gracilis (specifically Potentilla gracilis var. fastigiata or var. elmeri, which are highly characteristic of this area)

Informal Names

• Slender cinquefoil

• Graceful cinquefoil

• Northwest cinquefoil

• Five-finger cinquefoil

Key Characteristics

• The Flowers: Features bright, cheerful canary-yellow blossoms spanning about 0.5 to 0.75 inches across. Each flower has 5 heart-shaped petals with a distinct, shallow notch at the outer tip, surrounding a dense central hub of fuzzy yellow stamens.

• Five-Finger Foliage: The common name "cinquefoil" translates to "five leaves." Its fan-like (palmate) compound leaves are deeply divided into 5 to 7 finger-like leaflets radiating from a central point, looking remarkably like a hand or a wild strawberry leaf. The edges of the leaflets are sharply and neatly serrated.

• Growth Habit: A sturdy, variable perennial herb that shoots up slender, erect, hairy green-to-reddish stems usually standing between 1 and 2.5 feet tall, positioning the flower clusters perfectly above the surrounding marsh grasses.

Notable Significance

• The Rose Connection: Though it is low-growing and herbaceous, it belongs proudly to the Rose family (Rosaceae). Its open, symmetrical floral layout closely mimics primitive wild roses and strawberries.

• Pollinator Generalist: The flat, wide-open shape of the blossom serves as a literal landing pad for a massive variety of generalist pollinators. It is heavily visited by native solitary bees, hoverflies, and small butterflies.

• Traditional Astringent: Various Native American tribes across the West historically valued the tannin-rich root systems of Potentilla species for traditional medicinal uses, often utilizing root decoctions as an herbal wash or astringent to soothe skin irritations.

Locations Found

• Habitat: A lover of open, damp, and sunny ecosystems. It flourishes beautifully in moist montane meadows, along the gravelly edges of streams, near mountain fens, and in seasonally wet roadside ditches.

• Elevation Range: Widespread and highly common throughout the Pacific Northwest and California mountains. It thrives across the Southern Cascade and Sierra Nevada ranges at elevations from 3,000 up to 8,500 feet, making the lush, damp flats of Mineral an absolute stronghold.
