About this seed

Why gardeners choose this variety

The rounded flowers of double hollyhocks can give a narrow vertical planting a richly layered appearance. This is a different effect from the open faces of single forms, even though both belong to the same cottage-garden tradition. Mixed colors add variation as the eye moves up and between flowering stems.

A plain fence or simple wall can provide a background that lets those petal layers remain visible. Leave adequate space for each plant's leaves and eventual stem rather than crowding seedlings to imitate the phrase dense bloom. Flower abundance depends on the plant and its growing conditions, not the product name alone. Allow time for establishment and enjoy the developing display as part of a longer seasonal planting.

Self-sows yearly for full blooming rows each spring

Seeds drop after bloom season and sprout new dense hollyhock stalks each year, only light thinning to keep rows balanced and full.

Stalks fully covered with ruffled double blooms
