Broadleaf Weed – Filaree

(Erodium cicutarium)

Filaree – also sometimes referred to as Redstem Filaree, Common Storksbill,
Heronsbill, Alfilaria, Pin-weed and Pin-grass – is a winter annual or biennial broadleaf weed. Preferring dry, sandy soils, Erodium cicutarium is commonly found in open grassy areas, lawns, waste grounds, and along sidewalks and roadsides. Filaree can be found throughout much of the continental United States, with the exception of Florida and Mississippi.

Identifying Filaree -

Filaree is a winter annual or biennial that overwinters as a horizontally growing basal rosette. Its leaves and stems are often reddish in color, and its stems grow low, are hairy and sparsely leaved. The leaflets are deeply cut, nearly to the mid-vein, with stem leaves being slightly smaller in size but also compound and deeply cut. Filaree has a shallow taproot with a secondary fibrous root system.

Blooming from March through November, Filaree features flowers with 5 purple or purplish pink petals, 5 green, hairy sepals, 10 stamens, and 5 united styles with purple stigmas in the center. Only 1 or 2 flowers are in bloom at the same time. Reproduction is by seed.

Filaree Control -

Cultural weed control methods are largely ineffective against Filaree. Once established in turfgrass, physical removal is no longer an option for complete control. Professionally applied herbicides are the only way to ensure total removal.
