Filaree

 Filaree in Escondido

Filaree (Erodium) is the plant that took me some time to identify. It's very common in Southern California but only in the spring. It grows pretty much everywhere where the common grass grows. Filaree blooms in small delicate 5 petal flowers. The leaves are serrated though there are several species of filaree with different degree of serration. Later in the season  one can see long seedpods. They resemble storkbill which  is another name of this plant.
