Description

The Derrick Cook perennial Himalayan Geranium makes excellent ground cover, with large white flowers veined with purple, earlier than other varieties.

This Himalayan geranium has a spreading and bushy habit and fast growth. It has deciduous, palmate, cut leaves, medium green, and cup-shaped flowers with 5 petals, single, 3-4cm (1-2in) in diameter, white veined with purple. It blooms from May to July.

The 'Derrick Cook' Himalayan Geranium is very accommodating and thrives in rich, humus-bearing and well-drained soil. It adapts to all light conditions but blooms more in the sun.

The 'Derrick Cook' Himalayan Geranium is easy to grow and fits everywhere: shrub and perennial beds, rockeries, slopes, or containers.

Planting and care

The perennial Geranium himalayense Derrick Cook should be planted from September to April in rich and well-drained soil, preferably in the sun. Leave spacing of 20cm (8in) in all directions. Weed carefully while waiting for the plant to occupy the space. Mulch in summer to keep the soil cool. Divide the clumps every 5 years after flowering to rejuvenate and propagate them. Cut back the faded stems to encourage a second flowering. Watch out for slugs!
