25 Seeds Dark Black Purple Hollyhock Perennial Flowers

Add dramatic height and deep, velvety color to your garden with these Dark Black Purple Hollyhock seeds. Hollyhocks (Alcea rosea) are classic cottage garden favorites, producing tall spires of large, saucer-shaped blooms that attract bees and butterflies. This variety features nearly black, dark purple blossoms that create a stunning contrast against green foliage and bright flowers.

Hollyhocks are versatile in the garden, ideal for back borders, fence lines, or as a striking focal point. They readily self-seed, ensuring years of beauty. While often grown as biennials, they can behave as short-lived perennials in favorable conditions. Enjoy cut flowers for vivid indoor arrangements or leave them to attract pollinators throughout the summer.
