Plant details

This is a classic English cottage garden flower, often seen growing against the house or in groups supported with strong stakes near a garden wall. Hollyhocks are strictly perennial plants, but the older they are the greater the risk of rust disfiguring their leaves, and it is more usual to raise them as biennials, sowing one summer to flower the next before being cleared. Single-flowered strains are more elegant and typical of the race, than the heavy double forms whose blooms tend to be spoiled by wind and rain. Formerly called Althaea rosea.
