Carolina geranium is a semi-erect biennial, but may also occur as a winter or summer annual. A basal rosette is formed in the initial stages of plant growth followed by stem elongation and branching as the plant matures. The erect stems are covered with hair and may reach up to 28 inches in height. The alternate leaves are on long petioles, rounded in appearance and deeply divided into 5 to 9 toothed segments. The flowers of Carolina geranium have 5 white to pink petals and form in clusters at the tips of stems and branches. The fruit of the plant is less than 3 mm long with an elongated shape, tapering to a point.
