Geranium multiflorum is a 1 to 3 m (3.3 to 9.8 ft) tall, many-branched shrub in the Geraniaceae (geranium) family. The leaves, typically oval, 4.5 to 7 cm (1.8 to 2.8 in) long and 1.5 to 3 cm (0.6 to 1.2 in) wide, have 7 to 11 veins, grayish silky hairs, especially on the lower surface, and 7 to 15 teeth on each side. Flowers are in clusters of 25 to 50 and have 5 white petals 10 to 15 mm (0.4 to 0.6 in) long with purple veins or bases. One reddish brown seed, about 2 mm (0.06 in) long. is contained in each carpel body (the seed-containing section of the fruit). The carpel body, about 3 mm (1 in) long, is topped with an elongated style 14 to 20 mm (0.6 to 0.8 in) long, which twists to aid dispersal.
