Why Grow Double Hollyhock?
Double hollyhocks bring height, drama, and classic beauty to the garden, making them a favourite for cottage-style borders and cut flower gardens. In addition to their ornamental appeal, hollyhocks belong to the mallow family and share the gentle, soothing qualities found in many traditional apothecary plants. They are pollinator-friendly, deer resistant, and well suited to long-term garden plantings.
