How to Plant Hollyhocks

Choose full sun and well-drained soil with room for tall flower stalks. Sow and thin according to the package directions. Space plants to support airflow and place them where their mature height will not shade lower-growing flowers.

Hollyhocks may flower in the first year when started early, but biennial plants often establish foliage before blooming the following season. Plants can self-sow where conditions permit, so manage spent flower heads if volunteer seedlings are not wanted.

Garden Use

Hollyhock flowers add vertical structure and can provide forage for visiting bees and butterflies. Tall stalks may benefit from a sheltered site or support in windy gardens.
