Filaree are winter annual members of the geranium family. Filaree has a shallow coarse tap root. The feather like compound densely-haired leaves form from a prostrate basal rosette. The leaves consist of 5 - 9 opposite leaflets which are deeply cut. The leaves of white stem filaree are broader and the leaflets are less deeply cut than red stem filaree.
Stems are also hairy, grow low and spreading.
The flowers of filarees form umbrella shaped clusters which are pink to purplish in color and contain 5 petals. Filaree reproduces by seed. Filaree is found in Canada and the United States and is abundant on the west coast. Filaree is usually found on dry sandy soils. For physical removal of plants in turfgrass areas, hoe or dig up as soon as rosettes are recognized.
