    Description

    • a low-growing, densely matted plant with fern-like leaves that grow in a rosette form
    • leaves have reddish stems and are covered in fine hairs
    • flower stalks support two to twelve vibrant pink/purple flowers with five petals and a long, beak-like fruit
    • other common names for redstem filaree include cranesbill, heronsbill and storksbill due to the resemblance of the flower and fruit to a bird’s head

    Location

    • commonly grows in planting beds and lawn areas

    Life Cycle

    • winter annual or biennial that germinates in moist soil in temperatures between 40-70°F (spring to fall)
    • seedlings that germinate late in the year remain dormant as a rosette during winter months
    • growth resumes in early spring, and plants flower from mid-spring to mid-summer

    IPM Recommendations

    • Hand-pull plants in planting beds prior to seed maturation.
    • Shallow tillage or hoeing will control young plants in planting beds.
    • Apply a mulch layer 3 inches deep on planting beds to reduce seed germination.
    • Competition for light from taller desired vegetation can help control weedy patches.
    • Apply an appropriate pre-emergent herbicide prior to seed germination or apply an appropriate post-emergent herbicide directly to target weeds.
