Tall plants 2 m (6') high are loaded with fully double flowers in rose, salmon, buff, yellow, red or white with a cushion center. Hollyhock is a biennial that will not bloom until the second year, then they flower heavily, produce seed and die. For this reason we recommend planting seed two years in a row. After that, as hollyhocks reseed readily, they will soon become a permanent fixture in the garden. Plants do best in the garden when spaced at least 45 cm (30") apart. Reliably hardy to Zone 3.

How To Grow
110 seeds/gram. Seed can be started indoors in a soil-less mix in March. Germinate at 18 C (65 F) for 21-28 days then grow on under lights before hardening off and transplanting to a sunny site in the garden. Avoid higher temperatures as it affects germination success. Direct outdoor sowings can be done May to August. Space mature plants 75 cm (30") apart in the garden.
