Hollyhock may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden in early summer, or planted from potted plants. Sowing Seed Indoors: Sow indoors 6-8 weeks before the last frost. In frost-free areas, sow in late winter indoors to flower the same year.
Hollyhocks are fully hardy and flower in the second year after sowing. They are short-lived perennials and available in both single and double flowers.
Hollyhocks are easy to grow, although many varieties are biennial and take two years from seed to flower. Some bloom the first year if planted early enough, and other varieties are considered to be short-lived perennials.. . . . .364011235451!]
