Geranium carolinianum is a species of geranium known by the common name Carolina crane's-bill, or Carolina geranium. It is an annual herb native to North America, where it is widespread and grows in many types of habitat. There are two varieties; G. carolinianum var. carolinianum and G. carolinianum var. sphaerospermum. It may be considered an invasive species outside the southeastern United States. Geranium carolinianum has erect pubescent or hairy stems, typically colored pink or red. There are two leaves per node on each stem, which may be either alternate or opposite. The stem is not succulent, and not nutrient-rich as a source of calories for herbivores. The palm-shaped leaves are several centimeters wide, ranging between 3–8 cm (1.2–3.1 in). They are usually divided into five segments, which are each subdivided into elegantly-pointed lobes and secondary lobes. The fine hairs on the surface of the leaves may give them a silvery or grey hue, with the underlying color shifting from green to a deep red at maturity.
