Slender cinquefoil, also known as graceful cinquefoil, is a sweet and long-lived perennial with cheerful pale to yellow, five-petaled flowers that are an important source of nectar for small pollinators who lack the girth to open more complicated flowers. Attractive, sharply-divided, semi-evergreen foliage, with diagnostic silvery-white undersides, sprawls gracefully from its woody crown and hosts many native butterflies.

Gardening with Slender Cinquefoil: This adorable cinquefoil prefers full sun to partial shade with seasonally wet to moist soils that are well-drained and rich with organic matter. If planted in drier or more exposed locations, it may require infrequent, but deep supplemental water during the peak of the summer drought. Companion plants include ash and cascara trees, and other moisture-loving wildflowers like blue-eyed grass, lupine, and Oregon iris.
