How to plant Hollyhock seeds

26 Hollyhocks

Hollyhocks are sturdy and stately, old fashioned plants. They bloom over a long summer season. Flowers attract hummingbirds and butterflies. Plants will usually reseed and return year after year.

Double Flowered

Alcea rosea

Large double, flattened peony-shaped flowers. Plants are biennials or short-lived perennials. Average garden height is 5-7 ft. Grown in rich soil with plenty of water, plants can reach a whopping 10-12 ft. tall. We are pleased to offer the following excellent, often seldom seen varieties.

Chater's Double Series

NEW FOR 1847

William Chater (1802-1885) through his Saffron Walden Nursery in England, revolutionized the growing of hollyhocks upon the release of the 1847 seed catalog. Offered for the first time, were reliably double hollyhock flowers of uncommon size and substance, in colors not previously seen.

Chater's hollyhocks are biennials or short-lived perennials. Plants bulk up the first season - bigger plants produce more flowers - and then explode into bloom in late spring or summer of the second year. In astonishingly rapid fashion, plant stems elongate and produce a wealth of large, plump buds. Spectacular, towering, flowering stalks follow. Cut back after bloom, plants will flower again in late summer and fall. Seeds allowed to mature near the end of the season, will often self-sow. Plants are winter hardy to zone 3.

How to Plant and Grow Hollyhock

Bee introduces how to plant

Plant Hollyhock Seeds: Sow seeds in 2 in. pots or cell packs, press into soil and lightly cover. Kept at 70-75° F., germination is in 14-28 days. Can direct sow into prepared seed beds in groups of 3-4 seeds, spaced 2-3 ft. apart. Thin to strongest plant.

Grow Hollyhock: Full sun, part sun in hottest climates. Hollyhock plants perform best in fertile soil with regular moisture. Irrigate from below and provide good air circulation. True perennial hollyhocks noted in description. Most are biennials, or short-lived perennials. Many hollyhocks flower the first season when started early. After flowering cut back plants hard, to within a few in. of the ground. Continue to water and fertilize. Plants repeat bloom in late summer and fall. Single flower hollyhocks attract hummingbirds and butterflies. Hollyhock plants will often self sow.
