A classic of traditional English flower gardens, this plant produces tall stalks covered with spectacular single flowers, in shades ranging from deep brownish-purple to an almost pure black. This drought-tolerant perennial blooms throughout the summer, creating an elegant and dramatic effect at the back of mixed borders or as a focal point.

Reaching up to 2 m (6.5 ft) in height, the black hollyhock is a strong pollinator attractant, especially for bees, butterflies, and hummingbirds. Although short-lived, it self-seeds easily, ensuring its presence in the garden for several years.
