About

Geranium sang. var. striatum is a cranesbill in the family Geraniaceae and a member of the genus Geranium. It shows the genus’s palmately cleft, broadly circular leaves and bears five-petalled flowers that commonly display veining, flowering from June to September. Plants will grow in a wide range of soils provided they are not waterlogged. Propagation is by semi-ripe cuttings in summer, by seed, or by division in autumn or spring.

In the garden

Geranium sang. var. striatum belongs to the Geraniaceae and sits within a genus that occurs across temperate regions and in mountain areas of the tropics. Like many cranesbills, it carries palmately divided leaves and five-petalled blooms that are often veined; these appear between June and September. The genus includes annuals, biennials and perennials, and this variety shares the structural traits common to those groups. Give the plant any soil that drains freely; the key requirement is to avoid waterlogged conditions. Good drainage is more important than a particular soil type. Propagate by semi-ripe cuttings taken in summer, by seed sown in suitable season, or by lifting and dividing clumps in autumn or spring to rejuvenate plants and increase stock. In UK gardens it suits temperate sites where the soil does not remain soggy, and it integrates well with mixed herbaceous borders or planted under taller, deciduous shrubs that allow spring light to reach it. Expect a reliable flowering window from June to September, and increase numbers by division or cutting when you need more plants for repeats or edging runs.
