In the garden
Geranium pratense 'Mrs Kendall Clark' is a perennial in the Geraniaceae, native to Belgium, that produces a substantial clump to roughly 1.2 m. The foliage is rounded and palmately lobed, and the cultivar is valued for a long flowering run from June to September. It suits both exposed and sheltered sites in the UK. Position it in full sun to partial shade. Soil can be loam, chalk, sand or clay and may be acid, neutral or alkaline; the key requirement is that the ground drains well without becoming bone-dry. It is winter-hardy to H5–H7 (hardy to fully hardy in UK terms), so plants will tolerate a range of winter conditions across most of the country. Aspect does not need to be restricted, so you can site it in north- or south-facing borders. Use this cranesbill in mixed herbaceous borders, cottage garden schemes or wildflower meadows where a spreading, mound-forming habit is useful. Allow clumps space to spread so they can form drifts; in a back border or meadow setting a stand of Geranium pratense 'Mrs Kendall Clark' will provide sustained interest through the summer months from June to September.

Care notes
Pruning and caring for Geranium pratense 'Mrs Kendall Clark'
- Cultivation
- Among the least demanding of perennials, asking only for reasonable drainage and an open position. Shear the whole plant back hard after the first flush and water it in; most kinds then produce fresh foliage and a second showing by late summer.
- Pruning
- Cut back to a low framework after the first flowering to renew the foliage and prompt repeat bloom. Tidy any remaining growth in late autumn or early spring.
- Propagation
- Divide in spring or autumn. Many species self-seed freely, and basal cuttings suit cultivars that resent disturbance.
- Pest resistance
- Largely untroubled, though vine weevil grubs attack the roots of container plants and sawfly larvae occasionally strip leaves.
- Disease resistance
- Powdery mildew and rust may appear on congested plants in a dry summer; shearing back usually resolves both.
