The flowers are individually rare, usually in pairs. The flower usually grows on a long stalk. This allows the geraniums in their natural habitats as an equal to most others, as high-growing plants from which they are surrounded in this manner and ensure their pollination. The hermaphroditic, but somewhat flower is five parts. The five green, free, and often hairy petals are always true to a projecting point. You close one of the first flower bud. When developing after pollination of the flower of the fruit larger, the sepals and protect the approach for the large fruit. The five free petals are nailed in some species.

When the flowers of the forest-bill stork is disk flowers, the flowers in the form of leaves and debris on places growing Ruprecht herb is known however as a funnel flowers. Accordingly, different insects involved in pollination. The flowers in the forest with the stork's beak easily accessible nectar are visited by hoverflies, bees and butterflies. To reach the nectar of the Ruprecht Krauts on the other hand only langrüsselige bees and butterflies.
