Description

The Chater's Double Hollyhock (also known by its Latin names, Alcea rosea and Althaea rosea) is a hardy perennial plant that produces large spikes of multicoloured double flowers. Belonging to the Mallow family, it is typical of country gardens.

Widely found in rural areas, Hollyhocks are often grown at the back of flower beds or against a wall for protection against strong winds. Indeed, from a small cluster of rounded leaves, tall flower stalks quickly shoot up towards the sky, reaching heights of 2 to 2.5 m (6 ft 7 in to 8 ft).

Their large pompom-like flowers with ruffled edges resemble peonies and bloom in a staggered fashion from June to August. Throughout this period, they will attract bees and butterflies to your garden.

Planting and care

Sow Hollyhocks from May to July. You have to wait for 15 to 20 days for the young shoots to appear. Transplant the young plants when they have reached a height of 7 cm (2.8 in), at a distance of 20 cm (7.9 in) from each other. The following spring, place them in your flower beds at a distance of 40 to 50 cm (15.7 to 19.7 in). Make sure to stake them if the location is not protected from the wind. Avoid planting Hollyhocks in the same spot for several years in a row to prevent the appearance of rust (a parasitic fungus visible as orange powder) on the foliage.
