Practical Weed Science for the Field Scout: Corn and Soybean
Geranium, Carolina (Geranium carolinianum)
Winter annual broadleaf
A winter annual or more often a biennial, forming a basal rosette initially with subsequent stem elongation and branching as the plant matures. Seedlings have cotyledons that are hairy, kidney shaped, green above and pink below. Mature plants have stems that are usually pink to red in color and densely hairy. Leaves are alternate near the base, opposite above, and hairy on both surfaces. Leaves are rounded in appearance and deeply (palmately) divided into five to nine segments, each of which is also lobed or toothed. The fruit is an elongated beak that gives this structure the appearance of a crane's bill, which is also another common name of this weed.
