These beautiful purple blooms come from a very common weed growing close the ground called Storksbill or redstem filaree (Erodium cicutarium) and making spiral sticker seeds at end of season. They resemble a whorl of serrated leaves. The beautiful dark purple of the pistil and anthers are especially striking. The size of the blooms are about the size of a dime. Silent Valley Resort.
