DESCRIPTION:
Filaree plants are low-growing, cool season annual broadleaf plants. They can either grow erect or have spreading prostrate stems 3 to 12 inches (7.5 - 30 cm) long. In the early stages, leaves form a rosette close to the ground. The three species of filaree can be distinguished from each other by their leaf shape. Leaves of whitestem filaree are toothed, leaves of redstem filaree are deeply cut or dissected, and leaves of broadleaf filaree are lobed. Flowers resemble those of geranium and are rose purple. The fruit is long and needlelike. At maturity the fruit separates into five parts, each having a tail that coils spirally as the seed matures and dries.
