About plant names...

Rough-fruited cinquefoil is a Eurasian native. It was introduced to North America prior to 1900, and it has become widespread. It is considered a noxious weed in some localities.

Identification: Plants are up to 20" (50 cm) high, with hairy stems and palmlike leaf clusters. Each cluster has five to seven hairy leaflets, each 2-4" (5-10 cm) × ½-1" (1.3-2.5 cm), with many small teeth. Flowers have five petals and are about ½" (1.5 cm) in diameter. They are cream-colored, pale yellow, or yellow, with a yellow center and black spots on the anthers. Fruits are dark brown achenes (dried fruits) with branched ridges, hence the name “rough-fruited.”

This cinquefoil is found in grasslands, shrubby areas, open forest, roadsides, abandoned fields, and waste areas.
