25 Seeds Double Violet Hollyhock Perennial Flower

The Double Violet Hollyhock is a stunning heirloom perennial that produces tall spires of fully double, rich violet blooms. Its old-fashioned charm brings dramatic height and cottage garden elegance to sunny borders and backdrops.

Thriving in full sun and well-draining soil, this classic plant can reach 5-7 feet, attracting bees and butterflies. While often treated as a biennial, it self-seeds readily to provide years of color. Ideal for cut flower arrangements and creating vertical interest in the garden.
