Hollyhock, Jet Black (Alcea rosea)

Jet Black Hollyhock is a dramatic beauty valued for its visual impact and garden versatility. Admired for its dark maroon to near-black flower spikes, this biennial can grow up to 8 feet tall under ideal conditions, with its towering stems creating bold vertical accents in gardens. The plant prefers full sun and well-drained soil and is particularly suited to cottage gardens, perennial borders, and tall-back plantings where its height and dark color create contrast against lighter foliage and flowers.

With its velvety dark blooms, this Jet Black variety provides an unexpected focal point among other perennials, while its tall flower spikes support pollinators like bees and butterflies. In European gardens, Alcea rosea has long symbolized fertility and the pursuit of beauty, in part because of its towering stature and prolific flowering.
