Native to Europe, but possibly introduced to North America as a garden plant. It now is present across the northern half of the United States and southern Canada.
A perennial weed that reproduces from seeds, but spreads by rhizomes as well. It is found commonly in turf and landscape, thriving best in poorly maintained conditions. It also is found along roadsides and in disturbed sites, and in meadows, wooded areas, and open fields. Many cinquefoils are sold as ornamental ground coverings, and can become invasive from the site where planted.
Mature plants are erect to somewhat prostrate, and this species differs from other species by having no stolons and by having up to 7 leaflets on the compound leaves. Leaflets are elongate oval, and are much narrower and shorter than on other species. They have a dense covering of silvery-white hairs on their lower surface. The leaflets have 3 to 5 deeply notched teeth on their outer half, and smooth margins along their lower half. Flowers are bright yellow and are produced on long stalks that arise from the leaf axils. The 5 petals are well separated at their bases, and surround the prominent stamens.
Characteristicts Important to Control:
Physical removal is generally ineffective due to the underground rhizomes. A systemic herbicide will be effective in controlling the entire plant. Good turf health and vigor will reduce the ability for the weed to grow well in the turf.
