description_en: Genus of about 300 species of annuals, biennials, and herbaceous, semi-evergreen, and evergreen, sometimes tuberous perennials, often confused with the genus Pelargonium (which is commonly, though incorrectly, known as geranium). Cranesbills are found in all except very wet habitats throughout temperate regions. The leaves, usually rounded or 5-pointed, are palmately lobed, the divisions often further lobed and toothed; they are frequently aromatic or interestingly marked, textured, or coloured, sometimes also colouring well in autumn. The basal leaves are often arranged in loose, sometimes overwintering or semi-evergreen rosettes; the stem leaves are usually smaller, with fewer lobes. Flowers are white, pink, purple, or blue, usually saucer-shaped, sometimes flat or star-shaped, with petals sometimes reflexed and often contrastingly veined or marked; they are mostly borne in diffuse or dense cymes or umbel- or panicle-like inflorescences. Cranesbills are generally long-lived, versatile, and undemanding plants. Compact perennials, to about 15cm (6in) tall, are good for a rock garden; trailing, spreading, or mat-forming plants are effective as ground cover in a woodland or wild garden. Taller, clump-forming species and hybrids are suitable for a border or among shrubs.

hardiness_en: Fully hardy to half hardy.

cultivation_en:

propagation_en: Sow seed of hardy species in containers outdoors as soon as ripe or in spring. Sow seed of half-hardy species at 13-18°C (55-64°F) in spring. Divide in spring. Increase by basal cuttings, taken in early or mid-spring, and root with bottom heat.

pests_en: May be damaged by vine weevil larvae, sawfly larvae, slugs, and snails. Viruses and downy mildew may also be troublesome. In dry conditions, powdery mildew may be a problem.
