Alcea rosea, the common hollyhock, is an ornamental dicot flowering plant in the family Malvaceae.
Alcea rosea is variously described as a biennial (having a two-year life cycle), as an annual, or as a short-lived perennial.
[citation needed] The plants are easily grown from seed, and readily self-seed.
However, tender plants, whether young from seed or from old stock, may be wiped out by slugs and snails.
