Argentina anserina (L.) Rydb. Silverweed, silverweed cinquefoil
Silverweed is a member of the rose family. Argentina means silver, a reference to the silvery white color of the undersides of the leaves; anserina means "pertaining to geese," possibly a reference to its growth on land grazed by geese. It is native to the cooler areas of North America. Identification: Silverweed is a low, creeping plant. Leaf clusters are about 5-10″ (12-25 cm) long. Each leaflet is about 1-2″ (2.5-5 cm) long and ½″ (1.3 cm) wide. The spiky appearance of the leaves is quite unique. Flowers are yellow,[1] with five petals. There is only one other member of this genus, Argentina ededii. It is hard to tell these apart, but silverweed occurs inland, while A. egedii occurs near salt water.
