|Filaree (Erodium cicutarium)|
DESCRIPTION: Annual to 15". Flowers pinkish-violet, with 5 petals. Ripening fruit pod sticks up (2") and gives the plant its other common name -- heron's bill. Leaves are finely divided (fern-like), basal, and grow to 4" long. Geraniaceae (Geranium) Family.
NATURAL HISTORY: Introduced species from southern Europe. Flowers bloom spring through summer. As the pod matures and dries, it twists and falls off. When the seed pod becomes moist again, it untwists, driving the point of the seed pod into the ground.
