Potentilla biennis, commonly known as biennial cinquefoil or Greene’s cinquefoil, is a perennial herb native to a variety of habitats including open woodlands, grasslands, and meadows in western North America, from northwestern Canada to the southwestern United States. It typically grows to a height of 1-2 feet (0.3-0.6 meters) with a similar spread. This species is characterized by its pinnate leaves and yellow flowers that bloom from late spring to early summer, providing a modest display of color in the garden. The flowers are not particularly showy, but they do attract pollinators.

Biennial cinquefoil is appreciated for its drought tolerance and its ability to thrive in a range of soil conditions, from moist to dry, making it a versatile choice for xeriscaping and naturalized plantings. It is often used in restoration projects, as it can help stabilize soil and support local ecosystems. In cultivation, it requires minimal maintenance, tolerating both full sun and partial shade. While it is not typically afflicted by serious diseases or pests, it can spread quite readily by seed, which may be a concern in some areas.CC BY-SA 4.0
