Hollyhock Seeds grow into biennial or short-lived perennial plants with tall, upright stems and large, cup-shaped flowers in shades of pink, red, white, yellow, or purple. They thrive in temperate climates with full sun and well-draining, fertile soil. Hollyhocks are ideal for garden beds, borders, cottage-style gardens, and trellis or wall planting, providing vertical interest and long-lasting blooms from mid-summer through early fall.
