Many people grow domesticated Potentilla cultivars. They’re a common ornamental plant in Alberta gardens. There are several Potentilla species found in K-Country, but by far the most common is Shrubby Cinquefoil, which is the source species for many ornamental cultivars. Both Potentilla fruticosa and Dasiphora floribunda have been used to refer to this species. Taxonomic revisions have resulted in the transfer of the species from the genus Potentilla to the genus Dasiphora. Therefore, Dasiphora floribunda is now considered the accepted name for this species, while Potentilla fruticosa is considered a synonym.
We just find it easier to call it Shrubby Cinquefoil, or just plain ole’ Potentilla, even though technically, we’re now wrong. There are many Potentialla species in the Rockies, but Shrubby Cinquefoil is the only woody one. It closely resembles garden variety Potentialla, since most were bred from this species.
Appearance and Habitat:
Shrubby Cinquefoil displays a tenacity and resilience that allows it to flourish in diverse habitats. This deciduous perennial shrub showcases a compact and bushy growth habit. Its small, serrated leaves form a dense foliage that persists throughout the growing season. This subspecies exhibits an impressive array of flower colors, including vibrant yellows, pinks, oranges, and whites, with yellow being far the most common. The blossoms appear in profusion, clustered at the branch ends, captivating the eyes and attracting pollinators with their beauty and nectar.
Ecological Significance and Adaptability:
Shrubby Cinquefoil finds its niche in a variety of environments. It thrives in meadows, open woodlands, and subalpine regions (VERY close to alpine pictured at right), displaying adaptability to varying soil conditions, moisture levels, and altitudes. This versatility contributes to the subspecies’ ability to colonize and establish itself in different ecological niches.
Shrubby Cinquefoil plays a vital role in the ecological balance of K-Country. Its robust growth and ability to thrive in challenging environments make it a valuable component of the plant community. The dense foliage provides cover and nesting sites for birds and small mammals, while the flowers serve as a crucial nectar source for pollinators, including bees and butterflies. The subsequent production of seeds ensures the subspecies’ continued distribution and genetic diversity. Small mammals, such as voles and rabbits, feed on the stems and leaves.
Furthermore, Shrubby Cinquefoil exhibits impressive adaptability to disturbances such as fire, grazing, and soil erosion. Its ability to resprout vigorously from the root system after disturbances helps stabilize soil and initiates the process of ecological recovery. This adaptability contributes to the subspecies’ persistence and its capacity to withstand environmental challenges.
