Geranium carolinianum
herbCarolina geranium (Geranium carolinianum) is a native wild cranesbill, a low, branching winter annual or biennial of lawns, fields, and waste ground, with rounded, deeply cut, palmate leaves and tiny pale-pink five-petaled flowers followed by the long, beak-like seed pods that give cranesbills their name. Modest and weedy, it stays under a foot tall and is grown - or simply tolerated and gathered - as a traditional astringent herb, the leaves and aerial parts used. It is tough, self-sowing, and undemanding, greening up in fall or early spring and finishing by early summer.

Carolina geranium needs almost nothing: average to poor, well-drained soil in full sun to part shade. As a winter annual it is typically sown in fall, germinating in cool weather to overwinter as a small rosette and flower in spring, though spring sowing also works in cooler regions. Surface-sow and barely cover the seed, thinning to about 8 in. apart. It tolerates poor, dry soil and needs no feeding, and it self-sows readily to return on its own. It is short-lived and finishes by early summer heat, so enjoy and harvest it in the cooler months.

Gather the leaves and tender aerial parts in spring while the plant is lush and before it flowers and sets its beaked seed pods, when the astringent quality is best. Use them fresh or dry them quickly in a shaded, airy place. The plant is small, so harvest whole tops; it finishes with the onset of summer heat, so take what you need in the cool season.
Carolina geranium is grown as a traditional herb rather than a food - the leaves and aerial parts are rich in astringent tannins. In the garden it is mainly a tolerated native wildflower of the cool season, a small cranesbill that feeds early pollinators and self-sows to return each year.
