Slender Cinquefoil is a common, somewhat quiet but easy to grow long lived native perennial. Palmate leaves are conspicuously serrated on long stems. In early to mid summer 20″ stems support multiple clumps of sunny single yellow flowers. Full sun to part shade in average to enriched soil. Water to establish the first season then let it go with seasonal rainfall. Wild looking perennial that shines in borders, among shrubs and along the urban wild lands interface. Very pretty clustered at the foot of Holodiscus whose bloom is simultaneous. Loved by pollinators and an important food source for many butterflies. Native from SW. British Columbia south to San Diego County California. Often found in Ponderosa pine forests. Blooms much more heavily in full sun and improves under cultivation. Winter deciduous. Little deer resistance. Rose family. These are seed raised from Willamette Valley populations so it is the local form. Oregon native plant.
We’ve grown this stunning perennial for years but there has always been some question to the exact species. All we know is that for foliage there really is nothing like it. Large spreading rosettes of pure metallic silver pinnate leaves are gorgeous all season. In summer and not very prolifically sporadic spikes of small yellow flowers rise above the foliage. Not the point of this plant and they can be removed if they are a distraction. To 1′ tall and forming a large patch in RICH, moisture retentive soil in full sun to light shade. Established plants can get by with much less water. Performance is equally as good in either position. Completely deciduous in winter. Beautiful leaves.
