Scientific NameGeranium dissectum
Synonyms (former Scientific Names):
Dissected geranium are found growing in sunlight or shade. Seeds germinate or sprouts emerge in spring and grow through the summer. Flowering occurs from May until frost. Above-ground foliage dies back during winter. Plants are common in tilled areas such as gardens or in lawns, especially where previous disturbance has occurred.
Lower leaves are alternate and produce a basal rosette while upper leaves are opposite. Leaves are deeply divided or dissected and have rough hairy surfaces on both sides. Leaves are long-stalked, palmatisect with narrow 1.5-3 mm and acute straps.
Dissected geranium is similar to Carolina geranium in every way except the sepals and pistil of flowers. While the hairs on Carolina geranium are mostly nonglandular, the dissected geranium has glandular sepals and carpel.

Flowers of dissected geranium are purplish, small, and short-peduncled (5-15 mm). Petals are notched and shorter than the calyx. Sepals are covered with gland-tipped hairs. The flower structure of this weed plant contains 1 smooth valve. It is long, narrow, divided into 5 filiform one-seeded mericarps, with glandular erect hairs on the beak.
Seed are reticulate and connected to a long style that rotates with drying cycles and helps seed penetrate material on the soil surface.
