Other Common Names:
This freely branching biennial, flowers from May until August. Although usually biennial, they can also be found as winter or summer annuals.
The leaves are alternate towards the bottom forming a basal rosette, while leaves on flowering stems are opposite. Hairy on both sides, leaves grow from 2.5 to 7 cm in diameter and are usually deeply divided into 5 to 9 lobed or toothed segments. The leaves are usually green but often have red hues. The round stems are green, light pink, or red and are densely covered in hair. Two stipules are present at the base of leaf stalks.
Carolina geranium is distinguished from dovefoot geranium and smallflower geranium by its dissected leaves and sepals with long awn-like tips. Carolina geranium is very similar to dissected geranium and differs only in that sepals and carpels of dissected geranium are totally glandular while in Carolina geranium these are mostly nonglandular.
