Description

This fresh and lively hollyhock or Alcea rosea Halo White displays all summer long its flowers with large, simple, white corollas with a broad, bright yellow central halo. Considered a perennial but often grown as a biennial, it develops bushy mounds in two years, from which large, remarkably heavy blooming stems emerge. This cottage garden staple prefers poor, stony soils, is drought resistant and prefers warm spots.

Hollyhock is also known by its Latin name of Althaea rosea or Alcea rosea. It also has many common names that have been adapted to the different accents of our French regions. Of the family Malvaceae, it is native to Asia Minor and often naturalizes in cottage gardens, wastelands, mounds of earth. 'Halo White' is an original variety with bicoloured blooms. This unbranched, upright plant can reach 1.5 m to 2 m in height. It forms a branched rosette of stems covered with rough, rounded leaves, from which robust, fast-growing flower stems emerge. These spike-shaped inflorescences are covered with many large buds that bloom, from bottom to top, into big flowers with single corollas whose texture reflects the light marvellously. They are bicoloured, pure white with bright yellow centres. Its flowering period is staggered from June to August. Their crinkled texture reflects the light beautifully. They are bi-coloured, pure white with dark maroon centres. Throughout this whole period, they will attract bees and butterflies to your garden. The flowers then give way to a large number of fruit, filled with seeds that spontaneously reseed in the most unexpected areas, which the plant seems to choose by itself: at the foot of walls, in poor and stony soil, in wall crevices, etc... 

 

Widespread in abandoned gardens or in wastelands in our countryside, the hollyhock is often grown at the back of beds or placed against a wall to protect it from strong winds. The fresh look and heavy blooming nature of this variety n will allow you to make superb associations with pink, red or white, single or double flowered varieties. They go well with the airy flowers of baby's breath, for example. Hollyhock is an edible plant: the flower buds can be eaten raw in salads and the young leaves can be eaten raw or cooked.

Hollyhock is both an ornamental and medicinal plant. Its seeds are used to produce a siccative oil. Rich in mucilages, it is a great demulcent, emollient, laxative, aperitif and it also relieves dry coughs. Its properties are nevertheless attenuated compared to those of its cousin the common marshmallow (Althea officinalis).

Planting and care

Sow hollyhocks from May to July. It takes 15 to 20 days for the young shoots to appear. Transplant the young plants when they have reached a height of 7 cm, 20 cm apart. In the following spring, place them in your beds, spacing them 40 to 50 cm apart. Staking is required if the area is not sheltered from winds. Avoid planting hollyhocks several years in a row in the same spot to prevent rust from appearing (a parasitic fungus in the form of orange powder) on the foliage.
